Singer Demi Lovato and boyfriend actor Wilmer Valderrama are reportedly planning to enter wedlock.
Valderrama, 33, purchased a stunning ring from America's house of design Tiffany's in Pasadena, California and acted "really excited and happy".
"Yes, Wilmer did buy a ring here. We all talked about it afterwards because he was so darn nice," showbizspy.com quoted a source from the store as saying.
While the source couldn't confirm that the item was an engagement ring, the ring itself was said to be "extremely stunning".
"He chose a really classic, beautiful ring. Demi is going to be a happy girl when she gets it. He didn't say what it was for but he was really excited and happy - he seemed like any other guy getting ready to pop the question," she said.
