New York, April 18 – Given the fairly high rate of movie costar love affairs – Penelope Cruz/Tom Cruise followed by Penelope Cruz/Matthew McConaughey, for instance – Demi Moore seems awfully confident in her relationship with Ashton Kutcher. The two have been very friendly with Kutcher’s A Lot Like Love costar Amanda Peet, and at the film’s premiere, Demi handed him off to her easily. Ashton and Demi came together, and walked halfway up the red carpet holding hands, where they met Amanda. Demi then said, “I’ll see you guys inside”, and headed into the theater. Ashton then took Amanda’s hand and said to us, “My movie girlfriend”, and pulled her over to pose for photos. Of course, while Amanda Peet is younger than Demi, at 33, she’s still older than Ashton.
