Rob hangs out with his Brit friends Marcus, Jack, Nettie and Michaela.

Robert Pattinson knows there's nothing like a day at the beach!

The 26-year-old Twilight hunk enjoyed a day out and about in Malibu yesterday without girlfriend Kristen Stewart, accompanied instead by four pals (two guys and two gals). So, what kind of seaside activities R.Pattz and his gang get into?

The friends began their day paddleboarding in the ocean, a source tells E! News. At about 7 p.m., the group went to the Malibu Seafood restaurant for dinner.

The source says that Pattinson, dressed in black shorts, a gray hoodie and sunglasses, and his group "spent about and hour and a half in the restaurant, messing around, having a great time."

The group went back to a Malibu beach house, which is said to be the home of Stewart's mom, and stayed in the rest of the night.

The source added, "Everyone had a great day, and you could tell they were having a fun time."
