Idris Elba surprised fans when he brought along his pregnant girlfriend Naiyana Garth on the red carpet at the Golden Globes Sunday night.

According to reports, the 41-year-old actor and his makeup artist have been dating since March and confirmed Garth's pregnancy for the first time at the awards.

Elba looked dapper in a blue three-piece suit with a white shirt. He was photographed with his arm wrapped around his girlfriend. Garth looked stunning showing off her baby bump in a floor-length, black gown by British maternity designer, Tiffany Rose. See photos here:

Elba was nominated Best Performance by an Actor in a Motion Picture for his role in Mandela: Long Walk to Freedom. He did not win, however, as the award went to Matthew McConaughey for his role in Dallas Buyers Club.

Speaking previously about how he transitioned into character for the movie, Elba told the The Daily Mail he spent a night on Robben Island, locked in a cell next to the one where Nelson Mandela was imprisoned for 18 years.

"I wanted the audience to know what it was like once Mandela and his colleagues were jailed and the crowds dissipated," he said.

"It was a s***hole," Elba said. "I had a thin blanket for a mattress and that's all there was between me and the concrete floor. They gave me a bowl. I had no water, nothing to drink at all.

"I was wearing my sweats and what not. I had two iPads to document myself and a cell phone."
