Taylor Swift and Conor Kennedy aren't the only ones nursing breakup wounds these days. Downton Abbey's sexy Lady Mary, British actress Michelle Dockery, 30, kicked her rebound boyfriend, Holby City's Joseph Millson, 28, to the curb after five months of dating.

Dockery, who brought Millson with her to last month's Emmy Awards, where she was nominated for Outstanding Lead Actress in a Drama Series, split with her beau of three years, architect Trent Davies, earlier this year, and reportedly isn't ready to face another long-term relationship.

That doesn't seem to soften the blow for Millson, however, who tweeted his despair over the recent turn of events. "Just wait for someone worth being in a relationship with, stop wasting your time on the ones who don't deserve you," Millson tweeted.

A friend confirmed Millson's frame of mind. "He's heartbroken. The split was unexpected and it's still very raw for him," the source said. Millson was reportedly married with two children before he left his family to be with Dockery, reports the Sunday Mirror.
