Above is Idina Menzel at the Billboard Music Awards last night, where she introduced Mariah Carey’s performance. I almost didn’t recognize her at first because she looks so different with lighter hair! Plus she’s lost weight. Idina, 43, is always pretty, but I really prefer her with darker hair. This look doesn’t suit her. The styling is throwing it off too. Indina is wearing custom Badgley Mischka which… goes with her 90s styling. I wish she would go back to brunette. Killer necklace though, it’s Efva Attling.

Here’s what Idina looked like at the Vanity Fair Oscars party. She’s much more striking as a brunette. It’s just hair though and she can always change it again.

I’m adding in a few more random Billboard Music Awards attendees here and we’ll have more fashion throughout the morning. First off we have Charli XCX in a vintage gown by an unknown designer. She doesn’t look as oddball as she has at past events, but she doesn’t look like she’s having fun either. Charli was nominated along with Iggy Azalea in several categories for their hit “Fancy,” which won for top rap song. I feel like “rap” should be in quotation marks there.

Jennette McCurdy was extra in a sparkly blue strapless mermaid style gown that was too much for this event. She also switched up her hair, going from blonde to darker, although she did it a few months ago. At least her former Sam & Cat costar Ariana Grande wasn’t there. Jennette has admitted that they butted heads on set but claims that their relationship was “misconstrued.” I got the impression that they can’t stand each other.

Estelle was in a lace Galia Lahav gown for the red carpet and she switched it up to a Amanda Wakeley vest and pants with a Bibhu Mohapatra belt for her performance. I liked her pantsuit for the performance much better than this gown. She did a medley of “Conqueror” and “You’re So Beautiful” from the show Empire along with stars Jussie Smollett and Bryshere Gray. You can see her performance on JustJared.

Celine Dion was really working a green Thierry Mugler gown with a high thigh slit and a diagonal single strap. She looks incredible. This is just the right look for a music event.

Also in Thierry Mugler we have E!’s Giuliana Rancic. I am not liking her new hair, I think the extensions are bad, but I have to say that the dress is really cool. It’s a half mini, half long dress and somehow it works, maybe because the details are so subtle and understated. I’m a sucker for metallic piping.
