Flo Rida Spanks Kate Upton [VIDEO]: 'Low' Rapper Smacks Sports Illustrated Swimsuit Cover Model on Backside During Samsung Spring 2013 Launch Party, Upton Considers Teenager's Prom Invite

Rapper Flo Rida isn't afraid to go for it. This was the case at Samsung's Spring 2013 Launch Party when the "Low" singer spanked Sports Illustrated cover model Kate Upton on stage. Yup, you heard it right, Flo Rida went for it while performing on stage. The lanky, blonde bombshell was dancing on stage while the rapper was performing and Flo Rida reached back and smacked the 20-year-old model on the rear end.

On Wednesday March 20, Flo Rida was getting hot and heavy on stage rapping for the crowd and apparently model Kate Upton was enjoying the performance so much she joined the rapper on stage. In the video shot by TMZ, Upton was clearly enjoying herself dancing along on stage, when Flo Rida smacked her on the butt at one point. No one even seemed to blink an eye though and the spank seemed to be in good fun. It should be noted that it's hard to tell if he did really spank her as his hand is blocked by fans, but it certainly seemed like he did. As far as we know, Upton had no problem with the smack, as she seemed to take it in stride and kept on dancing. You can check out the video from TMZ below.

Upton recently was on the cover of Sports Illustrated's swimsuit issue for the second year in the row. The supermodel is quickly becoming one of the top models in the world. Upton also was recently in the news when a teenager asked her to prom. Jake Davidson, a 17-year-old high school senior made the bold move of asking Upton to prom in a YouTube video that quickly went viral. Upton played along when she tweeted a response to the teenager, "You can call me Katie if you want! How could I turn down that video! I'll check my schedule ;)"

Good for that young man, maybe if he becomes more confident one day he can try to pull off what Flo Rida did on stage. However, we wouldn't recommend many guys trying that, especially since Upton could have had a big problem with Flo Rida's butt spank (and rightfully so!). So don't try that home gentleman.
