Christina Aguilera got the most romantic Valentine's Day present. Her boyfriend, film producer Matt Rutler, proposed and Xtina accepted. She was quick to show off the ring, too.

Can't stop singing 'Let It Go' from Disney's 'Frozen'? Neither can we. And neither can the incredibly talented Off-Broadway actress Christina Bianco, who performed a hilarious parody of pop divas -- everyone from Demi Lovato to Alanis Morissette -- singing the now-iconic Disney tune.

One of the greatest gifts that music can give us, when done exceptionally well, is bring us joy, sadness or take us back to a moment in time. As I was listening to A Great Big World's 'Say Something' on the air today, it reminded me of a song that was one of the biggest records from 1981.

Christina Aguilera has ousted R. Kelly…sort of! Xtina replaced R. in a new remix and new studio version of Lady Gaga's R&B hit 'Do What U Want.' The divatastic rendition has landed – so how is it?

On tonight’s episode of ‘The Voice,’ the Top 8 sang their little hearts out as they got one step closer to that glorious finish line.
