Adam Lambert has performed a rendition of Rihanna's hit track 'Stay'.

The singer posted a video clip of himself covering the song whilst rehearsing, with Lambert showcasing his vocal talents.

The video, which was posted on Keek, sees Lambert sitting down on some steps whilst wearing a baseball cap backwards.

Responding to a fan's question about the clip, Lambert replied: "It was a preview! It was rehearsal. More to come!"

As previously reported, Adam Lambert commentated on the Grammys last night (February 10) via his Twitter account.

He praised the likes of performers Ed Sheeran and Sir Elton John, as well as saying about Rihanna:

"Best she's ever sounded!! Wow. Full of such beautiful and haunting emotion."
