What's this about Demi Lovato tagging along Wilmer Valderrama to her Sonny with a Chance Costar's wedding?

Not only did Demi attend the wedding of former Disney pal Tiffany Thornton with rumored beau Wilmer, the singer was also said to have caught the bride's bouquet. Well, as saying goes, whoever catches the bouquet in a wedding means they'll be tying the knot next. Would this be a premonition for another wedding that is soon to happen?

Demi Lovato and Wilmer Valderrama have been dating since Lovato's break up with Joe Jonas in 2010. Despite the age difference of 11 years with Wilmer being older, the couple have managed to stay strong until June of 2011.

This could have been another added stress that caused Demi to fall into treatment for her bipolar and eating disorder.

Now it looks like the couple are back together with photographs scattered all over the web of their latest "canoodling" session. During a house bash of Seth McFarlane, the creator of Family Guy, which happened last October 22, the couple were making all efforts to show people they were back together.

Photographs of the singer and the actor kissing were taken outside Valderrama's home the morning after the Halloween party where both were said to have attended.

Valderrama known for his reputation for dating young celebrities and being a blabber mouth about details in the sack, would he be able to keep up the boyfriend act with Lovato this time around?

Aside from being Lovato's wedding date last Saturday at Hot Springs, Ark, the couple were also spotted together at Las Vegas for the Latin Grammy Awards. Demi Lovato was scheduled to perform and although the singer ducked out from the red carpet, her boyfriend Valderrama was interviewed by E! News.

What did Wilmer have to say then?

"It's going to be a great night," says the actor when asked what he had to say about the rumors of him and Lovato dating. Valderrama remains to be mum about the issues and so does Lovato.

As for wedding bells, everyone is hoping that if Demi Lovato does decide to walk down the aisle, it would be a marriage that would last longer than 72 days.
