British beauty Sienna Miller debuted her baby bump on the red carpet in New York last night (February 14th).

Arriving at The Ever Changing Face of Beauty event, Miller wowed onlookers with her demure appearance that comprised a sleeveless black dress and small protruding tummy.

Although the actress’s pregnancy was confirmed last month, this was the first time audiences had the opportunity to get a good glance at the 30-year-old’s bump.

The star’s attire was flawless as she matched her gown with gold jewellery, including a chunky bracelet, necklaces and earnings.

Miller pinned her long locks into a stylish chignon and only time will tell if she will pass on her penchant for top fashion choices to her little one, whom she conceived with The Boat That Rocked actor, Tom Sturridge.

Her 26-year-old beau was not spotted at the elite event, but rumours have surfaced suggesting the pair may be set to wed after beginning a relationship last year.

Miller is set to appear in a mirage of films in 2012, including Hippie Hippie Shake, Yellow and Two Jacks.
