Jake Gyllenhaal and Natalie Portman are back together.

The couple were seen getting friendly at Matthew McConaughey's star-studded Malibu barbecue last week.

An eye witness is quoted in Britain's Daily Mirror newspaper as saying: "They strolled on the beach together, laughing and having a great time talking. He was very attentive to her and seemed to be hanging on every word she said." "Brokeback Mountain" star Jake has become good friends with wild bachelor Matthew McConaughey since the two actors started training with cycling legend Lance Armstrong for the New York marathon.

However, Jake was on his best behaviour at the barbecue and is believed to have stayed by Natalie's side for most of the evening.
