Bruno Mars is thrilled his track Grenade is being "recognised" because he worked on it for so long.

The singer received six Grammy Awards nominations last night, with Grenade in the running for the Record of the Year and Song of the Year. The track also won Bruno a mention in the Best Pop Solo Performance category.

Bruno is particularly thrilled to be vying for the gongs as the tune is one of his favourites.

"I think [the company we're in is] all that matters right there, that's the win for us. Especially with Grenade actually, we worked really hard on the song for like three months, tearing up pieces of paper, trying to get that song to where it is today and it's nice that that's being recognised," he said. "We're proud of that song and we hope that we remain victorious the night of the Grammys."

Bruno will battle it out against acts including Adele, Katy Perry and Mumford & Sons for the Record of the Year Prize.

Actress-and-singer Taraji P. Henson was delighted to be at the event, which took place in Los Angeles and was broadcast on television.

She revealed some of the award nominations and said the only letdown of the evening what that she didn't get to spend time with Lady Gaga.

"It's a lot of fun. My only disappointment is that I didn't get to Lady Gaga because my dream is to be one of her dancers," she laughed backstage to ET. "She is like a movement and I just love everything she represents, she's amazing for me. If this acting thing doesn't work out look for me on the Lady Gaga tour, I'm a monster."

The official awards ceremony will be held on February 12 at the Staples Center in Los Angeles.
