As things get smoother and smoother for Demi Lovato and boyfriend Wilmer Valderrama, wedding rumors start to spread.

The two began dating in 2010 but the relationship went on and off; but today, it seems that they have become stronger and are ready to take steps farther.

A source of Radar Online heard the "Neon Lights" singer talking to a salesclerk at Urban Home and Décor, saying that she wanted "her and her boyfriends' home to be warm and comfy". This statement suggested that they have moved in together. Haven't they?

She described her plans for their bedroom as something "romantic, dark, and passionate".

Last month, many speculated that the two had been engaged or secretly married because of the identical rings they wore that observers did not fail to notice in their separate Instagram posts last October 28.

Demi Lovato and Wilmer Valderrama wedding rumors started last year when Wilmer was seen buying a ring for Demi at Tiffany & Co. An observer told Mail Online that it "looked like an engagement ring" but it could also be just a "nice, expensive ring".

The tales even got bigger when Demi posted a photo with the ring on her finger and made a follow-up post: 'Sooooo I don't think I've ever been happier in my life than this very moment that I am fully living in....'

However, last January, reps of the singer-songwriter-actress confirmed with that news about an alleged proposal is not true.

Demi Lovato and Wilmer Valderrama wedding rumors will keep on circulating but they may remain just that - rumors. The couple is known for being very private about their romantic life.

In other news, the "Really Don't Care" singer responded to a fan's question whether she and Miley Cyrus are still friends. She answered this with: "We're like acquaintances." She explained, "I don't have anything in common with her anymore, and I wish her all the best."
