Khloe Kardashian is always the first one to stick up for her family members, and after hearing Jamie Foxx's jokes about Bruce Jenner at the iHeartRadio Music Awards this past Sunday, the reality starlet is coming to her stepdad's defense.

As you may remember, Foxx joked to the crowd, "We got some groundbreaking performances here, too, tonight. We got Bruce Jenner, who will be here doing some musical performances. He's doing a his-and-her duet all by himself." Bruce is currently transitioning from a man to a woman (he'll reportedly switch his name to Belinda and make his debut on the next season of Dancing With The Stars), and Foxx later quipped, "Look, I'm just busting your balls... while I still can." Rude!

"I just think it's a low blow," Khloe told The Insider the other day. "I think it's very mean, but you know, I wish him all the best. It is what it is. I just think — and I know Jamie, so I think that's also why that's a really low blow, but hey. Guess that's what he felt the need to do for a little press."

Yesterday Khloe made an appearance at Ulta Beauty in West Hills, and she definitely put her family drama behind her when she waved for the cameras. And not only do we love the smile on her face, but check out her hot bod! Clearly all those hours at the gym have been paying off!
