Zac Efron and Robert Pattinson enjoyed a fun night out together in LA recently.

The Hollywood hunks - who previously vied for teen heartthrob status - enjoyed an evening with seven pals at Pinz Bowling Alley in California, followed by drinks in nightspot Bootsy Bellows and appeared to be great friends and not at all competitive during their games.

A source told E! News: ''Zac was seen goofing around and Rob was not even trying, skipping his turn at one point. When they left some of the friends smoked cigarettes, while they all just laughed and talked.

''Rob and Zac both looked good and happy. Rob showed Zac something on his cell phone and they both started laughing. They were in really good moods.''

Robert shot to fame in vampire series The Twilight Saga while Zac became a heartthrob thanks to his role in High School Musical.

It had been claimed previously by gossip blog that Zac was jealous of Robert's success but those days are now clearly behind them.

The pair's night out comes a few days after the 'Twilight Saga' star enjoyed another night with his pal and the 'Bad Neighbours' star's new girlfriend Michelle Rodriguez at Chateau Marmont on Saturday (19.07.14).

Last year, Zac, 26, endured two stints in rehab for rumoured substance abuse and alcoholism and recently admitted his experiences taught him a lot and set him on the right path for the future.

He said: ''I am so happy now and I feel like I am in a great place.

''It was an interesting year and I learnt so many things, but the best part of it was being able to reflect upon my experiences and what I had learnt about myself and the kind of man I want to be.''
