After three years away from the spotlight, Gwyneth Paltrow is certainly making up for lost time.

The actress was back on the promotional trail last night with another glamorous red carpet appearance at a screening of her new film Iron Man at New York's Tribeca Grand Hotel.

Gwyneth, who has trotted around the globe in towering 7inch heels this month - Burberry boots in Berlin! Pacchini platforms in Paris! - didn't disappoint, arriving at the event in a pair of black patent Christian Louboutins.

But it was her daring little black dress, a thigh-skimming halter-neck number featuring large cut-outs, that really stole the show.

While Chris Martin was nowhere in sight after the couple vowed to never attend public events together, the 35-year-old wasn't short on support, with friends Liv Tyler and Helena Christensen turning out at the event.

Of Gwyneth's recent rotation of high heels, she says: "They were just fabulous. They were very tall but they weren't hard to walk in."
