Jennie Garth is "taking care of herself".
The mother-of-three's estranged husband, Twilight star Peter Facinelli, filed for divorce nearly five months ago after 11 years of marriage.
The 40-year-old star has lost a significant amount of weight recently.
Jennie attributes her weight loss to a dramatic diet and lifestyle change.
"I'm just taking care of myself: Eating less, exercising more, drinking a lot of coconut water," she told Us Weekly.
"I eat a lot of Greek yogurt: Greek yogurt in the morning, salads and proteins the rest of the day and maybe a cupcake if I've been a good girl. I don't believe in depriving yourself of things you want."
The former Beverly Hills, 90210 actress recently reunited with her co-star Luke Perry to film a TV commercial.
Jennie was struck by how much chemistry she still has with Luke.
"It was weird, it was like no time had passed and we were back on the set again," she said.
"We want to work together again because we really love each other and it would be nice to spend time together working. It's a good day at work when you're with people you know and that you like."
