Musician Anderson East and the country sweetheart were vacationing in the winter wonderland when he took a tumble and she had to get medical help.

"It wasn't quite the fun holiday trip they wanted, but they were still happy to be together and he's really happy she was there nursing him by his side and making sure he was OK," a source tells Us Weekly magazine.

Another insider claims East, 27, broke his collarbone, adding, "He's been in a lot of pain but (he is) going to rest and heal up now that they're back home (in Nashville, Tennessee)."

Lambert and East, real name Michael Cameron Anderson, have been dating for weeks, but they didn't go public with their romance until the New Year, when they both posted a photograph of them snuggling up to each other under a blanket at a party.

She captioned the snap: "The snuggle is real..."

Lambert and Blake Shelton ended their four-year marriage last summer (15).
