June 22 (UPI) -- Kate Beckinsale was spotted kissing 21-year-old actor Matt Rife in Los Angeles this week.
The 43-year-old actress started dating the actor and comedian following her split from husband Len Wiseman, according to Entertainment Tonight.
Beckinsale and Rife were seen locking lips Wednesday outside Villa Lounge in West Hollywood. Sources said the pair met through a mutual friend and are now "officially boyfriend and girlfriend."
"They quickly started flirting, went on their first date and it's continued since," an insider said.
"Everyone in Kate's circle loves Matt and are so supportive of this relationship," the source added. "He really is the sweetest guy and makes her so happy! Her entire family thinks he is the nicest and most lovely person."
People reported Beckinsale isn't fazed by her 22-year age difference with Rife, who is known for the MTV series Wild 'N On Tour.
"Kate is enjoying her life. She is dating and having fun," an insider said.
"She has been seeing Matt for the past few weeks. She really seems to like him," the source added. "She refers to him as an old soul. There is obviously a physical attraction too. The age difference doesn't matter to her. Matt is amazing to her."
Wiseman, who directed Beckinsale in Underworld, filed for divorce from the actress in October after 12 years of marriage. Beckinsale was previously wed to Michael Sheen, and shares 18-year-old daughter Lily Mo with the actor.
