Kelly Osbourne

Kelly Osbourne is going through a rough time after her split from her ex-fiance, Matthew Mosshart. The 'Fashion Police Star' has reportedly put herself in "food rehab" after gaining weight as a result of the breakup four months ago.

Lady Gaga and Kelly Osbourne have been publicly feuding for a while now, but the ladies proved that they finally made up and let bygones be bygones, posing for a cute and funny photo at a 2014 Oscars after party (March 2).

Kelly Osbourne just broke up with her fiance Matthew Mosshart. What better way to take the sting out of a broken heart than by hanging out and creating art...with Justin Bieber. Wait, what?

Kelly Osbourne is engaged to her boyfriend of two years, Matthew Mosshart. And if it seems like you've heard this story before, well ... you have.

And the Kelly Osbourne / Lady Gaga battle royale continues. This time Kelly Osbourne has called out Lady Gaga, once again, in her cover issue of Cosmo. Can't these ladies just let this beef die already? Apparently not.

E! 'Fashion Police' correspondent Kelly Osbourne was rushed to the hospital after suffering a seizure in the middle of filming.

Looks like the Osbournes are about to add to the clan -- Kelly has reportedly been "secretly engaged" to her boyfriend of over a year, chef Matthew Mosshart, for several weeks now.

Lady Gaga is getting another word in edgewise in the ongoing saga involving Kelly Osbourne and her mom Sharon Osbourne. After Sharon posted a response to Gaga's original open letter, the Mother Monster is back with another retort.

After Lady Gaga penned an open letter to Kelly Osbourne that essentially told her to stop being such a bitch (we're paraphrasing here), Sharon Osbourne jumped in to defend her daughter. As a result, insults are being hurled and fans on both sides are involved in heated slapfights. In other news: Timmy pulled Susan's hair during recess and now he has detention.
