Lindsay Price and Josh Radnor have split, Usmagazine.com has learned.
Radnor, 35, and Price, 32, first met on the set of his CBS sitcom How I Met Your Mother in 2007.
But they didn't begin seeing each other until last August.
"We've been friends for awhile, and we have mutual friends in common," she told Us in February.
Price also told Us she even met Radnor's mom.
"I have actually [met her], but it wasn't a 'situation,'" she told Us. "They were in town, and they all got together."
She was mum when asked for more details.
Said the star, "I'm so shy talking about that stuff!"
