rita ora calvin harris brit awardsRumors about Fifty Shades of Grey star Rita Ora's relationship with Scottish DJ Calvin Harris being on the rocks have been swirling for a few weeks now. And their most recent public appearance at the BRIT Awards this week only seems to be adding fuel to the fire.

The pair hit the red carpet looking stunning -- Rita in a yellow Prada gown with emerald green details -- but the singer/actress looked uncomfortable, tense, and far from her "usual bubbly self," reports The Daily Mail. Wuh-oh.

Maybe she's just tired after jetting all over the globe -- shooting Fifty Shades in Vancouver, posing for Material Girl in Miami, walking the runway for Milan Fashion Week before heading back to London ...? But given that in the shots she took solo, she looked noticeably happier or at least comfortable, it's no wonder the buzz is that she and Calvin are headed for splitsville.

The result of the Fifty Shades curse? Perhaps ... Or just the sadly common upshot of two entertainers who are too busy, important, and jet-set to keep their love life afloat.

Judging from this pic, would you guess Rita's relationship is on the rocks?
