Vienna Girardi: How I Lost 20 Pounds

Looking good is the best revenge!

Nearly a year after splitting from The Bachelor's Jake Pavelka, Vienna Girardi has a new man -- and a hot new figure.

As the 23-year-old reality star tells Us Weekly, she recently dropped the 20 lbs. she gained during her 2010 stint on the ABC series. Girardi's best body part? Her taut tummy.

"I love my stomach," she told Us at Thursday's Friends of El Faro Celebrity Poker Tournament in L.A., adding that she'd like to drop 15 more lbs. "I'm working on getting it back…I'm six pounds down and I have a few more to go. I'm working out with my trainer, Brian Peeler, and I started working out at Physique 57."

Girardi says the key to her weight loss success has been cardio training and a strict diet without starches or wheat.

When it comes to logging hours at the gym, "We do something different every week. Today we went to [L.A.'s] Runyon [Canyon], and I have gone to Runyon a million times but never like we did today. Not only was it 100 degrees out, but he literally made me run down the hill with my shoulders back and your core tight. Then, he made me run up the mountain on the steps. I was so sore by the end of the work out. Every 15 minutes, I was like 'I'm gonna pass out!'"

With Pavelka long out of the picture, Girardi has a new man who appreciates her curves: Bachelorette star Kasey Kahl, whom she began dating earlier this year.

Enduring a long distance relationship -- Girardi lives in L.A. and Kahl in Fresno, Calif., -- the couple work hard to make their romance work.

"We are so crazy about each other, Girardi gushes to Us. "The only thing we bicker about are [travel arrangements]. It's always like 'are you gonna drive here this weekend or am I gonna drive there this weekend?' But, it's a good bicker because we just want to be around each other!"

Khloe Kardashian: I'm "Massive" Next To Sisters

It's not easy being the "biggest" Kardashian sister.

In the new issue of Us Weekly, out Wednesday, Khloe Kardashian admits red carpet events with older sibs Kim and Kourtney can take their toll on her self esteem.

"They are 5-foot and 5-foot-2, so I look massive next to them," Khloe, who is 5-foot-10, tells Us. "Everyone expects me to be 9 feet tall and weigh 200 pounds [when they meet me]."

26-year-old Khloe -- whose mom Kris Jenner even criticized her weight in a recent episode of Khloe and Lamar - has "struggled with her weight since she was 8 years old," a family friend tells Us. "She was always taller and developed much broader shoulders than her petite sisters."

And the E! reality star, happily married to basketball star Lamar Odom for over a year, says she first gained weight following Kris' divorce from her late father, famed OJ Simpson trial attorney Robert Kardashian Sr.

"My brother [Rob] and I were always heavy. They gave us food to keep us comforted. All we did was eat crap," she recalls.

Classmates and even her mom's friends noticed that Khloe's older sisters Kim, 30, and Kourtney, 32, stayed skinny despite the family turmoil. "I had older women tell me, 'You should really work out,'" she explains. "It really got to me."

Her initial response? A teenaged Khloe hit the gym, working out three times a day and eating tiny meals. She went from a size 12 to 0.

"I started to get a positive response from people when I was losing weight," she admits.
