GOOP queen Gwyneth Paltrow has finally found something exclusive and expensive that she actually hates: the Met Gala.

The 'Iron Man 3' actress hit up the ball earlier this week with her husband, Coldplay frontman Chris Martin. Martin, however, opted not to walk the carpet with his lady, which she explained was because they like to keep their relationship as "private" as possible.

But despite not turning up the heat with her hubby, the Oscar winner was still too hot for her own good ... literally.

Paltrow was one of the few stars to sport long sleeves on the red carpet for the 2013 soiree, which was seemingly too warm for her liking.

"I'm never going again. It was so un-fun," Paltrow told USA Today. "It was boiling. It was too crowded. I did not enjoy it at all."

The gala was likely accommodating the more scantily-clad starlets on the scene -- after all, it'd be hard for someone like Miley Cyrus to wear mesh in cooler temps.

Maybe if Gwynnie had opted for that see-through number she wore to the 'Iron Man' premiere, she'd have had the "open windows" she needed to stay a bit more comfortable.
