Bethenny Frankel Size-4 Just 3 Wks After Baby

Just three weeks after giving birth to daughter Bryn, Real Housewives of New York's Bethenny Frankel is back to a size-4 swimsuit!

In the new issue of Us Weekly, Frankel, 39, reveals how she's already lost 29 of the 35 pounds she gained while pregnant with Bryn, born May 8.

"I don't believe in diets," says the chef and author of Naturally Thin, who wed Bryn's dad Jason Hoppy March 28.

Frankel stayed active while carrying Bryn, alternating yoga with 45-minute walks three times a week, and practiced portion control with a vegetarian diet.

Still healing since Bryn's C-section birth, the 122-pound star has decreased her walks to 30 minutes and continues to eat low-fat fare. A sample day's menu: a muffin and fruit for breakfast, a veggie sandwich and soup at lunch and BBQ chicken and a half a sweet potato for dinner.

Frankel admits to Us, "I'm still wearing maternity clothes, because they're comfortable." Still, she says, "I"m excited to get into my Louboutins again. No more swollen feet!"

Jill Zarin: Cried for 3 Days After Party Crashing

Jill Zarin tells UsMagazine.com she still can't get over the frosty reception she received surprising Ramona Singer, Alex McCord and Bethenny Frankel on vacation in the Virgin Islands.

"It was such a Mean Girls moment that I literally cried for like two or three days," she tells Us. "They didn't offer me a glass of water or a bathroom! We had just traveled nine hours, and they knew it. I had to pee! You have no idea what a schlep it was. Schlep doesn't even describe it!"

Zarin, 46, originally told Singer, 53, she wouldn't go on the trip -- which was to celebrate Singer's marriage vow renewal -- because of her feuds with Frankel, 39, and McCord, 36. But she tells Us she decided to swing by on her way to St. Bart's to declare: "'I'm here to make up with everybody!'"

Zarin says Singer and McCord refused to give her a chance to explain.

"Alex was the one to really throw me out," she tells Us. "If she said, 'I don't care‚' then Ramona would have had me stay. [And] why didn't Ramona say to Alex, 'Jill is my friend. She should have called, but I'm not throwing her out'?"

Says Zarin, "It was the most hurtful thing that's ever happened to me."

Showing off her curves in a light blue lace bikini, the supposedly 32-year-old reality TV starlet spent the afternoon catching some rays but avoided the pool in order to keep her trademark wig in top condition.

Before heading back to the city otherwise known as Hotlanta, Kim tweeted: “Can’t wait to get home to the A!!! Heading that way!! Flight delayed…!!! But I’m coming!”
