Robert Pattinson seems no longer a one-woman man anymore. After coming into limelight for dating Sean Penn's daughter Dylan Penn, Pattinson was spotted flirting and partying with actress Shanon Woodward.

According to Hollywoodlife.com, Pattinson was spotted having a good time with Woodward in Los Angeles. On Oct. 29, he joined Woodward at a club No Vacancy. "Gossip Girl" star Penn Badgley was also seen partying with R-Patz and Shanon.

Fans that spotted the star in the club tweeted, "Saw Robert Pattinson & Penn Badgley tonight. Penn refers to his dad as, "father." V interesting, archaic, and formal."

Pattinson was rumored dating Shanon in September. So were the two trying to rekindle their romance?

This month, Pattinson has been spotted partying on various occasions. On Oct. 25 he was at Chateau Marmont and before that he was caught doing drugs with Dylan Penn at Viper Room.

It is rumored that Pattinson is partying hard to keep his mind off Stewart. Many of his friends believe that Pattinson should keep away from partying as it is harming his image.

A source told Hollywoodlife.com, "Kristen broke his heart; he has not been the same since she cheated. His friends don't want him to party. His team doesn't want him to be defined by what club he goes to or what women he dates. They want him to be known for being one of the great actors of his generation. They don't want his future opportunities jeopardized."
