Demi Lovato catches bouquet at Tiffany Thornton wedding

Demi Lovato caught the bouquet at Tiffany Thornton's wedding.

The singer took to Twitter to congratulate her former Sonny with a Chance co-star, who wed Christopher Carney on Saturday.

"Such a beautiful day," Lovato tweeted. "Congrats to the new Mr. and Mrs Chris Carney!"

Lovato went on to say that she managed to take part in one of the ceremony's key events.

"P.S. Guess who got the bouquet?" she wrote. "ME!"

Earlier this month, Lovato revealed that she tried to "fake it" until she made it as part of her plan to get an early discharge from rehab.

Last month, the singer announced plans to go on tour in the US with a ten-date engagement that will kick off this week in Detroit.
