Is there a bikini war brewing between Kim Kardashian and her mom Kris Jenner? The two ladies posted similar Instagram pictures showing off their tight and toned bodies while on vacation. Jenner, 58, is reportedly in France while Kardashian, 33, is on her second honeymoon in Mexico with new husband Kanye West.

On Friday, Kardashian uploaded two photos showing off her toned belly as she relaxed by a pool. Shortly after Jenner uploaded her own photo showing off her killer body as she too relaxed by the water.

"Bonjour!!! #blessed #grateful #thankyouGod," Jenner captioned her photo.

This isn't the first time the mother and daughter have done very similar things. On a sneak peek of "Keeping Up With the Kardashians," the new bride was talking with a friend about taking pole dancing classes when Jenner overheard them and insisted on joining.

Kardashian complained to the camera that her mom is always trying to copy her, the Daily Mail reports.

"I think she is so funny and amazing. But my mom literally copies everything I do," Kardashian said.

"I posted the swimsuit picture and then mom posted a swimsuit picture right afterwards," she added, referring to a different time the two ladies posted similar photos. "I mean, I get it, but come on."

"You guys are having a MILF-off," Khloe Kardashian chimed in.

Khloe previously joked about Jenner "stalking" and copying her sister on a March episode of "Chelsea Lately." Khloe, who was a guest host, read a story about Justin Bieber and his dad partying together and said she didn't find the story that weird.

"I think the weirdest part about this whole story is this is so normal to me because... my mom basically tags around with Kim, follows her around, dresses like Kim, like I bought her mansion for her," she said.

"What is so weird to me is we are showing a picture of tattoos [Bieber and his dad], I got a freaking tattoo on my lower back, the b**ch [Kris] copied me and got the same one!" Khloe added.
