The actor, 23, accompanied actress Teresa Palmer, 24, to a screening of her upcoming flick Take Me Home Tonight on Thursday.
"There was definitely some hand-holding," a source tells PEOPLE of Efron and Palmer inside the screening's after-party at L.A.'s Pink Taco restaurant. "The two ate together and seemed really engaged in conversation. They seemed really into each other."
The source adds: "They weren't trying to hide their affection at all, even though they knew people were watching them."
But the night was just beginning.
Another source says Efron and Palmer went to Voyeur nightclub in West Hollywood. Efron "gave high-fives to his friends" and watched the barely dressed go-go dancers "slide up and down the wall" with "a huge smile on his face."
"Zac chatted with Teresa for awhile," the source says. "She leaned in close so she could hear over the music [while Zac was] smiling and slightly flirting with her. There was no overt PDA, but he was not shy about giving her leg the occasional touch."
Efron and his ex High School Musical girlfriend Hudgens, 22, called it quits in December after dating since 2006.

On her career: "I was very lucky to have a show for eight years. Now I can sit back and think about what I want."
On making comedies: "I love doing comedies. Theyre just as hard, if not harder, to make work, compared with a drama. You work 17 hours a day, and you have to try to make things different and funny and relatable onscreen all at the same time."
Black Swan director Darren Aronofksy on working with Mila: Shell try anything . . . [Mila is] very, very playfulreally willing to experiment."
RadarOnline claims that Tracy Morgan, who recently underwent a kidney transplant, shocked fans and media by admitting just last week it was his ex, Tanisha Hall, who gave him one of her kidneys, despite the fact he left her for another woman.
The site built its story around exclusive quotes from Morgans brother, James, and mom, Alicia Warden, who both said they were unaware that the 30 Rock star needed a transplant.
I just found out on the Internet last month that he had the operation, said his brother James. And his mom added, He didnt tell me about anything Someone came and told me they saw it on the Internet, so I was just as shocked.
Well, theres good reason they didnt know. Morgan and his relatives have been estranged for some time and frankly they probably shouldnt be commenting on his life.
Gossip Cop, however, has the real story directly from Morgan, who did NOT leave Hall for another woman after he received a kidney from her. The couple broke up well before the operation.
Morgan tells us exclusively, While I rarely engage in the rumor mill, the erroneous article on radaronline.com is disrespectful to those who have been so generous to me in a time of need and I feel obligated to set the record straight.
It saddens me that my estranged family felt the need to discuss my very personal situation without any facts, but the reality is that Tanisha Hall and I ended our relationship in October and have remained good friends. She was loving enough to give me one of her kidneys for the transplant I needed and I am forever grateful to her and her family for their support.
Don't misunderstand, we're totally happy for them if they are dating like the reports say, but c'mon! Twenty's a little young to get married, dontcha think?
The news coming out of the I Am Number Four press day is that stars Dianna Agron and Alex Pettyferare engaged. This was deduced by sources from the simple, thin diamond band Dianna was sporting on her left ring finger all afternoon. When she was asked about it, she told sources that her love life is "something I never like speaking [about]."
Coy much?! If celebs were more upfront, less rumors would get started, you know!
Neither of their reps are confirming or denying the news, but an anonymous source who's supposedly close to the pair says they're very "happy" about engagement.
If you're happy, we're happy for you but we still think he's too young to get married!
Justin Bieber is the subject of so many rumors, it must be exhausting for Perez Hilton to cut and paste them all.
What the blogger fails to do, unfortunately, is check to make sure theres an ounce of truth to some of the stuff he posts.
Todays supposed scoop: The teen pop idol might be hitting the mat with a gig at WrestleMania.
Biebers peers are talking with World Wrestling Entertainment to participate in WWEs biggest event of the year, WRESTLEMAINIA (sic) announces Hilton.
Were not sure what cross-over audience Just-Biebs and WWE might have, he adds. BUT, according to sources, talks have been ongoing for several months and a deal for Biebs to perform at the event may be reached soon.
Wait, there may be an imminent deal bringing together Bieber and pro wrestling?
Umm, no, dont count on it.
When Gossip Cop asked whether there was any truth to the rumor, a rep for Bieber said, None.
Charlie Sheen was dancing his ass off with THREE scantily clad women at the inception of his 36-hour cocaine fueled party binge last week -- and TMZ has the footage of Charlie LETTING LOOSE!!
The dancing went down after a boozy dinner a the home of Charlie's friend George Santo Pietro -- where the actor was accompanied by several porn stars and even a few non-professionals.
Just as shocking as Charlie's spastic MJ-esque impersonation -- a photo of a smiling Charlie showing off a mouthful of solid gold dental work. Captain Jack Sparrow would be proud!
Of course, Charlie's party marathon ended with a trip to the hospital ... followed by rehab.
As we all know, James Franco likes to walk to the beat of his own bizarre drum, and recently left audiences baffled at the Sundance Film Festival with a temporary art-installation that recreated episodes of Three's Company!
However, it must have gotten SOME people thinking, because now the actor has revealed that he currently has a stage adaptation of the ABC sitcom in the works, and hopes to have it off the ground within the next few years!
He explains:
"When we came here, then the 'Three's Company' people contacted us like, 'What's going on?' So we had a talk with them, and they realized what we're doing is a cool thing. Otherwise, there's no other circumstance where 'Three's Company' would ever play at the Sundance FilmFestival. They were like, 'Yes, we've been trying to figure out ways of bringing it back in some form or another. We want to do more projects with you.' So now, we're planning and this is serious 'Three's Company,' the off-Broadway play. I think it needs to be developed a little more, something a little different but connected to the original."
LOLz!
We don't even want to BEGIN to think about what kind of ca-raazy direction he is going to take this 'adaptation!'
But we're also kind of excited to see what becomes of it! Lord knows it's going to be weeeeeeird!
And will he HIMSELF be featured in the play?! We hope so!
Keep the ridiculousness coming, bb! We're obsessed!
