blonde rolling stones dinner Christina Aguilera matt rutler Osteria Mozza restaurant

It's no secret that lovebirds Christina Aguilera and Matt Rutler love Osteria Mozza pizzeria in LA.

With her arm around Rutler, Xtina strutted out of the eatery wearing a Rolling Stones tee, black leather jacket, leggings and sexy red heels. The Burlesque actress is so serious ... hope everything is ok with these two.

The Voice mentor seems to have smoothed out her blonde locks, and as always, is rockin' those red lips!
