Blooming in a floor length, form-fitting red dress, the 28-year-old happily smiled for the cameras at the Gotham Independent Film Awards at Cipriani on Wall Street. And when she turned to the side, her new curves could be clearly seen.
The couple married two years ago at Claridge's hotel in central London with celebrity guests in attendance including Elton John and Geri Halliwell. The bride wore a £30,000 fitted cream wedding dress created by Ricardo Tisci of Givenchy.
David wasn't by his wife's side at the cine awards, but she was joined by a host of glamorous VIPS. Model Agyness Deyn, who wore an olive-green suit, was also flying solo without her new husband, actor Giovanni Ribisi.
Actress Amy Adams wowed in a black asymmetric dress, while Emily Blunt contrasted hwer look in a flowing white dress with cut-out sections. The Devil Wears Prada actress was escorted by her actor and director husband John Krasinski.
Those picking up awards on the night included Matt Damon, who picked up a career award, and Jared Leto. The actor and 30 Seconds to Mars singer cut a striking figure on the red carpet as he picked up a gong for his documentary film Artifact.
Displaying a thinner physique than usual and with his hair scraped back and a thick-rimmed pair of glasses, he certainly stood out. But what was most noticeable was the star's lack of eyebrows. The 40-year-old had them removed for his role in new film The Dallas Buyers Club. Jared plays a HIV-positive transvestite in the film which also stars Jennifer Garner and Matthew McConaughey.
The DKNY model kept her blonde hair natural, tumbling loosely over her shoulders. And she finished the look with minimal makeup, with the exception of dramatic dark eyes.
Lara and her husband revealed two weeks ago they're starting a family. Little Britain star David, who has also featured on the judging panel of Britain's Got Talent, revealed the news on Twitter.
He said: "Some wonderful news. My beautiful wife Lara is pregnant. We are having a baby! It is due next year and we both couldn't be happier. Dx" The couple then released a joint statement that said: "We're very excited to announce we are expecting our first child. We're both absolutely thrilled but ask you to please respect our privacy during this precious time."
On her Twitter account model Lara already classifies herself as a mum, after the happy couple welcomed dog Bert into their lives earlier this year. She recently joked about the differences between looking after an animal and having a child: "a baby will probably never be as fun as Bert."
