There were plenty of noteworthy dresses on the Grammy Awards red carpet Sunday night, however, three of our favorite looks belonged to supportive significant others who let their loves take the spotlight outside — but joined them indoors for the party.

Fun.’s biggest (and possibly most famous) fan, Lena Dunham, showed support for her boyfriend, the band’s guitarist Jack Antonoff, in a radiant yellow dress (worn with Forevermark diamonds) that could be seen even in long shots of the auditorium. She not only got to return the favor Antonoff paid by cheering her on at the Golden Globes, but she also got face time with her Twitter pal Taylor Swift.

Justin Timberlake‘s wife Jessica Biel celebrated her man’s return to music from what may have been the most fun seat in the house. She complemented Timberlake’s “Suit and Tie” in a one-sleeve Oscar de la Renta gown, T-strap Casadei pumps and some serious Lorraine Schwartz earrings with 60 carats of diamonds, emeralds and amethysts.

And Carey Mulligan shyly supported husband Marcus Mumford as he took the stage twice to perform — though she whooped it up when his band won Album of the Year. She looked chic, as always, in a tailored black pantsuit and golden choker (both by Lanvin) and messy chignon.

We were excited to see all three stars in the audience, but we’re torn on whose look we liked best. So tell us: Which famous date was the best-dressed?
