Dinner for two! Rihanna and Chris Martin got dinner together on Sunday, June 8.

Rihanna, who looked more covered up than usual in a black long sleeve blouse and black skinny pants, joined the Coldplay frontman at Giorgio Baldi in Santa Monica, Calif.

According to X17online, the duo arrived separately around 9 p.m. and enjoyed each other's company for two hours sitting at a corner table at the Italian hotspot where Rihanna frequents regularly.

Gwyneth Paltrow's estranged husband kept his look casual, donning a T-shirt and jeans.

The pair are said to be just friends, and previously worked together on the 2012 track "Princess of China," off Coldplay's fifth studio album Mylo Xyloto. The "Diamonds" singer and Martin performed the single together at the 2012 Grammys.

Martin and Paltrow announced they were consciously uncoupling back in March, but have been spotted out together numerous times, even embracing one another with a kiss while out to dinner at Rustic Canyon in Santa Monica on May 21, an eyewitness tells Us Weekly. The spouses of 10 years were also spotted on Saturday, June 7, enjoying time in Malibu together with their daughter Apple.

Rihanna, meanwhile, has been keeping things friendly with ex Drake. After splitting yet again in March, the couple were spotted "smiling" at each other while out at NYC's VIP Room on June 1.
