Kim Kardashian glams up for her Vegas New Year's bash with suspiciously plumper lips

She looked her usual glamorous self as she arrived for a New Year's Eve party in Las Vegas.

But something seemed a little different about Kim Kardashian last night.

The reality star's lips looked suspiciously plumper as she arrived at Tao Nightclub in a sparkling white mini dress that left little to the imagination.

But it was her plump lips that really got people talking.

Covered in nude gloss, the reality star's lips appeared much larger than they did 18 months ago.

The star, who was hosting the nightclub's annual New Year's party, opted to keep things in the family by bringing her brother Rob Kardashian as her date.

And she was clearly missing the other members of her clan.

It's been a busy last few days for Kim who has been shooting a music video for her new record all week.

Earlier this week, she stunned fans when she stepped out with her long locks braided into corn rows.
