They also hit up Hollywood's Chateau Marmont on Friday evening, July 18. "They went there super late to try to avoid any crowd," the insider says of their weekend fun, adding that Efron's rumored girlfriend Michelle Rodriguez hung out with the pair before she and Efron left for her house.
"The Neighbors" star and the "Twilight" alum have become good friends and have been spending evenings out on the town together in recent weeks.
"Zac has gotten to know Rob more and more through mutual friends and they enjoy talking about what they're working on in the future," the source adds. "Zac really likes the movies that Rob is doing right now and Rob has so many questions about growing up in Hollywood like Zac did. They seem to really click."
In addition to their party time at Bootsy Bellows, Efron and Pattinson were also seen mingling outside of the Pinz Bowling Center in Studio City on Tuesday.
The is hardly the first time the Hollywood hotties have hung out. Kristen Stewart's ex attended Efron's private birthday celebrations at the Chateau Marmont in October.
