Just weeks away from her due date, The Fosters actress Sherri Saum is getting ready to welcome her twin boys into the world. So far, her pregnancy has consisted of long walks, elastic waistbands, and, of course, a lot of chocolate ice cream.

“[I've been craving] chocolate ice cream, which I love anyway,” she tells People. “But I love it a lot now!” The actress showed off her growing baby bump outfitted in a strapless black gown at the 25th Annual GLAAD Awards in Beverly Hills, where she not only revealed her cravings, but how she is staying in shape.

“My favorite thing is just the power of walking,” she explains. “I can only do 10 to 15 minutes now and light weights. I still try to do something every day to feel active.” And it seems to be working!

The 39-year-old and her husband of more than five years, Kamar de los Reyes, announced the happy news late last year and were caught off guard by the fact that Sherri’s actually pregnant with two babies!

“We were like, ‘Awesome — a baby!’ And then the next ultrasound the doctor said, ‘Uh … looks like there’s a freeloader in there hiding,’” Sherri explained to Access Hollywood (via People) this past January.

Talk about a surprise! But it seems like the mother-to-be has adjusted well to pregnancy with twins. Sherri has been doing her fair share of preparation including hitting the baby books. “I’ve been reading Twins Sleep Training,” she added. “I’m also going to read The Happiest Baby on theBlock.” By the time these two boys make their grand entrance in May, Sherri will be an expert!
