She's arrived! Gwyneth Paltrow turned heads for all the right reasons Friday night. The star attended Diane von Furstenberg's "Journey of a Dress" exhibition in L.A. wearing a plunging neckline black jumpsuit -- with husband Chris Martin by her side.

At the star-studded event, Paltrow, 41, took it to the next level in the cleavage-baring ensemble. The Iron Man 3 actress accessorized the look with a snakeskin clutch, bright red lips, and kept her blonde locks down for a sleek look.

Paltrow and her Coldplay beau, 36, were holding hands as they arrived, an eyewitness tells Us Weekly. The married couple of 10 years were also spotted laughing at one point, as Gwyneth kissed the rocker on the cheek. (The two are parents to daughter Apple, 9, and son Moses, 7.)

Other stars in attendance included Marisa Tomei, Paris Hilton, Rachel Zoe, Demi Moore, newly engaged Robin Wright, and Toby Maguire and his wife Jennifer Meyer. Meyer was really animated and happy, and ran over so she could hug Gwyneth hello, the insider added.
