Why Is Kim Kardashian On Kanye West's Workout Plan?

Kim Kardashian is determined to lose weight, she says, just a week after suffering a wardrobe malfunction in Santa Monica after wearing a dress that was apparently too small for her curves.

“I’m hoping to slim down a little bit, and I’m not afraid to say it,” Kardashian tells the new issue of Life & Style. “I think everyone goes up and down in whatever that comfortable love relationship phase is where you like to eat out, but now it’s time to get it together again.”

On Sept. 26, Kardashian was spotted at an event titled, "Midori Makeover Parlour," wearing a green velvet dress, and the back was clearly undone, revealing her bra, as her fastens struggled to stay put.

Prior to the event, Kardashian’s mother and manager, Kris Jenner, tried to fix the back of the dress, but to no avail. At the event, Kardashian made sure to take pictures from the front so the malfunction was not visible.

It seems Kardashian has put on weight since growing more comfortable in her relationship with rapper Kanye West, who she has been dating since April.

The two have been seen on numerous occasions going out to eat at various restaurants, which can quickly lead to weight gain if one is not careful about what they are consuming.

“She feels so comfortable around him — he loves her curves — she hasn’t been vigilant about dieting,” a friend told the magazine.

Kardashian was seen out on the beach in Miami on Wednesday in workout gear and went jogging with her sister Kourtney and "Real Housewives of Miami" star Larsa Pippen.

“How is it that @KourtneyKardash & I have the same amount of weight to lose but she just had a baby! SMH [shaking my head]help! LOL,” Kardashian tweeted Wednesday afternoon. Kourtney Kardashian gave birth to a girl three months ago.

The reality star apparently feels differently about her body than she did earlier this year, when Kardashian told British magazine Closer in an interview, "I was never going to be one of those skinny girls and now I've accepted my curvy shape, I feel so much better…You can't spend your life worrying about calories."
