Listen to Britney Spears on iHeartRadio

Britney Spears is taking a break from her Las Vegas "Piece of Me" show to watch her little sister Jamie Lynn walk down the aisle.  Photos have surfaced of pop superstar wearing a sparkling silver cocktail dress while attending Jamie Lynn's Friday nuptials at the Audubon Tea Room in New Orleans. 

"E! News" says the 32-year-old was there with her boyfriend David Lucado, as well as her two sons who were in the ceremony as ring bearers.  Britney sent a special message to Jamie Lynn on Twitter, telling her the wedding was "magical" and she was "so happy [she] could be a part" of her big day.  

Jamie Lynn tied the knot with her boyfriend James Watson.  It was her first wedding, but she was previously engaged to the father of her five-year-old daughter Maddie.
