From short and glimmery to fruity and funny,  musical stars hit some high and low fashion notes at the 51st annual Grammy Awards.

Just-about-to-pop pregnant hip-hopper M.I.A. performed her hit “Paper Planes” prancing around in a  polka-dot outfit with a sheer midriff that made her look like a bumble-bee.

Pop songstress Katy Perry summoned up memories of Carmen Miranda with a fruit-filled short mini dress featuring hanging bananas as she sang her breakout hit, “I Kissed A Girl.”

“The highlight of my night would probably have to be the looks on…faces when people saw my ridiculous outfit,” Perry said backstage later, sporting a more elegant mini pink lace dress.

Shimmery metallic dresses seemed popular, including ones worn by both Grammy winner Estelle – who nabbed a trophy for best rap/sung collaboration with Kanye West for her hit “American Boy,” — and actress/presenter Gwyneth Paltrow, wife of Coldplay frontman Chris Martin.

Rappers like T Pain wore outlandish hats and jumbo size glasses, while other male musicians, like former Led Zeppelin frontman Robert Plant, 60, who swept the Grammys with bluegrass queen Allison Krauss for their collaboration “Raising Sand,” stuck to the rocker-chic jeans formula. But he admitted  that the tight jeans look was getting harder to pull off at his age .

When asked backstage if he had future plans to work on anything with his former band, Plant, sporting his trademark long blond curls,  said to a reporter, “I don’t know how old you are, but you look older than me. You try doing ‘Communication Breakdown,’ in tight jeans!”
