(Cover) - EN Showbiz - Ryan Phillippe has been enjoying the bachelor lifestyle since splitting with Reese Witherspoon in 2007.

And the 37-year-old actor is said to now be dating a young blonde actress who is 17 years his junior.

Life & Style magazine claims that the Hollywood star has grown close to 20-year-old Paulina Slagter who he has been seen around town with in recent weeks.

The fledgling starlet is said to be trying to make a name for herself in Tinseltown and is happy to be on the arm of established actor.

"Paulina was on Entourage, and she's trying to do more acting," an insider told the publication. "She's always auditioning and doing modelling."

Although insiders say that Ryan has been seeing Paulina for a while, they maintain that the relationship will not be a long lasting one.

"It's nothing serious, it's just another girl," the source said.

Ryan has two children with Reese; Ava, 11, and Deacon, eight. He also dated Amanda Seyfried for a few months before splitting over the summer.

His ex-girlfriend Alexis Knapp gave birth to their baby girl Kailani back in July, the product of their short-lived relationship. (C) Cover Media
