The 'Lip Sync Battle' star - who is expecting her first child with husband John Legend - revealed she will be wearing a tailor-made frock to the glitzy music event which takes place tonight (15.02.16) at the Staples Centre in Los Angeles, and has required at least "a few fittings" to make an ensemble that works around her growing waist.

Speaking of her visits to the dressmaker, Chrissy shared: "They're different every time because I keep growing like crazy. I like to go really simple, usually, but we kind of want to have a moment and really have fun with it this year. I have a black option, a black lace, and a then a white option and I'm still thinking. (The dress) will embrace bump!

"The dress for me is kind of like, Oh gosh, what zips and what's comfortable? Because you have to sit in it obviously and you don't want to make any weird faces or anything when the camera comes to you. But we're looking at two very different options. I grow two inches every 12 days ... not that anyone's counting."

The 30-year-old model - whose husband has been nominated in three categories at the awards for Best Rap/Sung Collaboration for his track 'One Man Can Change the World' with Kanye West and Big Sean, Best Rap Song and Best Song Written for Visual Media for his hit 'Glory' - has teamed up with hair brand TRESemmé on their Beauty-Full Volume Collection and is looking forward to being more creative with her hair style.

Speaking at the launch in New York City, she said: "We are working with TRESemmé for my hair look and I'm really excited about that, I feel like that's kind of the fun part."
