Warner: 'Aniston has a nice butt'

Jackie Warner has revealed that she believes Jennifer Aniston has the best celebrity behind.

Warner, a fitness trainer on the reality TV series Work Out, spoke to Us Weekly about her pick for best celebrity behind.

"She's always wearing those little short dresses and that butt just goes boom," said Warner.

She continued: "I guarantee she's in the gym and she's doing a lot more than Pilates."

Warner went on to list other celebrities with great bodies, including Kelly Ripa, Gisele Bundchen, Gwen Stefani and Ryan Reynolds.
