With a new pop-up shop to promote it's no wonder Christina Milian was lapping up the attention when she stepped out in Los Angeles  - flashing a new diamond grill.

The 33-year-old singer bared her gem-encrusted teeth as she headed out to her car on Sunday ahead of launching her latest venture. 

But it wasn't just her sparkly gnashers and contrasting hot pink lipstick that caused a stir, her plunging, skin-tight dress was equally eye-catching.
