Kate Upton & Maksim Chmerkovskiy Split After Six Months

Kate Upton and Dancing with the Stars‘ Maksim Chmerkovskiy have split up after six months of dating, Us Weekly reports.

“They are really good friends still and speak all the time, but their schedules just made it too difficult and it fell apart,” an insider said of the 33-year-old dancer and 21-year-old model. “[Chmerkovskiy] has a lot of respect for her, but it just wasn’t working anymore.”
