Gwyneth Paltrow and Chris Martin are proving they are the friendliest of exes.

The 41-year-old actress and the 37-year-old Coldplay singer, who announced their split back in March after 10 years of marriage, attended the same party in L.A. last night.

Paltrow and Martin both hit author Vicky Vlachonis' The Body Doesn't Lie book launch party Thursday. While the former couple wasn't photographed together, each of them posed for pics with friends and other celebs who were in attendance at the bash.

Paltrow looked gorgeous in black shorts and a white, cap-sleeved coat top. Meanwhile, Martin looked handsome as usual in casual black pants and a navy T-shirt.

Paltrow mixed and mingled with BFF Cameron Diaz while Martin posed for photos with Vlachonis and Tobey Maguire's wife Jennifer Meyer. Other stars at the party included Nicole Richie, Benji Madden and Leslie Mann.

Earlier this week, rumors began spreading after Martin grabbed dinner with Alexa Chung. Despite swirling romance reports, the singer's rep confirmed to E! News that he and Chung are "not dating."
