Actress Jennie Garth admitted that seeing her ex-husband, Peter Facinelli, with his new girlfriend pains her after being married for 11 years to the "Twilight" star, according to People.

The former "Beverly Hills 90210" star announced her divorce in March and since then, Facinelli has been dating actress Jaimie Alexander. Garth told the publication, "I think there will come a time when it won't sting so bad. But I'm not quite there yet."

"You know, I am happy that he is happy, though," she added.

The 40-year-old also said that she is dating a man, however, she declined to reveal his name. She has been linked to HGTV's Antonio Ballatore, photographer Noah Abrams and businessman Jason Clarke, according to The Huffington Post.

She and Facinelli share three daughters: Luca, 15, Lola, 9, and Fiona, 5. The parents agreed to share custody over the holidays and Garth said, "We are co-parenting and getting the hang of it." 

Facinelli met Alexander while filming "Loosies," a film they co-starred in which came out in January, ABC News reported. They then went on to work together on "Nurse Jackie." The 38-year-old is 10 years older than the 28-year-old "Thor" actress. They also attended the New York City premiere of the last "Twilight" movie together.

On Nov. 30, Alexander confirmed to People that she is dating Facinelli.

"We've been friends forever and had a lot of mutual friends and we reconnected in the middle of the year," Alexander said. "It was one of those things where I'd been single for a very long time and he was going through a lot. We sort of bonded."   

"It's also something we don't want to give up on because I know how it makes me feel in my heart ... It makes me feel really good," she added. "He's a good guy with a great family and I couldn't be any luckier."
