Demi Lovato walked down the aisle on Saturday as a bridesmaid at her actress pal Tiffany Thornton's wedding.

Singer/actress Lovato got into the celebration spirit as her former Sonny With A Chance co-star married her partner Chris Carney in a romantic ceremony.

Lovato later took to her page to send her best wishes to Thornton, writing, "Had such an amazing day.... Congrats to the new Mr. And Mrs. Chris Carney. "

And the 19 year old, who is rumored to be dating actor Wilmer Valderrama, is convinced her love life is starting to shape up - after catching the bride's bouquet.

She adds, "Guess who caught the bouquet...... ME!!!!! :D"

Tradition has it the girl who catches the bride's bouquet will be the next to wed.
