Kate Upton 'splits from dancer Maksim Chmerkovskiy after six month romance'

Kate Upton appears to be back on the single's scene.

The 21-year-old Sports Illustrated Swimsuit model is said to have called it quits with Dancing With The Stars pro Maksim Chmerkovskiy.

Kate and the 33-year-old Maksim apparently had trouble keeping the relationship going with their busy schedules and so decided to break up, Us Weekly has reported.

It's over: Upton has been single since splitting from former Dancing With The Stars pro Maskim Chmerkovskiy in December after a six-month romance

'They are really good friends still and speak all the time, but their schedules just made it too difficult and it fell apart,' a source was quoted telling the magazine.

'[Chmerkovskiy] has a lot of respect for her, but it just wasn't working anymore.'

The couple hooked up in June, as reported in Us Weekly, and let the public in on their romance as they enjoyed a hand-in-hand stroll in New York's West Village on September 26.
