Singer Matthew Bellamy has a special muse on the way to give more inspiration to his music. The Muse front man is having his first baby with actress Kate Hudson and he dished about the news to ET's Nancy O'Dell backstage at the Grammys on Sunday night.

"That will be another surprise," Matthew said of the baby's gender, which the couple has opted not to find out.

Matthew dished that not knowing the sex of their child makes choosing a name twice as difficult.

"We're starting to agree on names," said Matthew. "Hopefully we'll think of something last minute."

Justin Bieber didn't go home with an award but he was definitely one of the biggest winners of the night. His new documentary 'Never Say Never' pulled in over $30 million at the box office this weekend, and Nancy O'Dell broke the news to the music phenomenon backstage.

"Really? Are you sure?" said Bieber. "It's all because of my fans. I couldn't do it without them."

Lady Antebellum brought home four awards from the show including Record of the Year for Need You Now, and ET captured lead vocalist Hillary Scott being congratulated by her mom over the phone.

"You're on 'Entertainment Tonight,'" Hillary told her mom.

"Oh my God!" said the singer's mother, who went on to gush about how proud she is of her daughter.
