She called them her "Metball LOLs!" and there's no doubt that Brit singer Lily Allen was laughing out loud at the Metropolitan Museum of Art's Costume Institute Gala in NYC, Monday, May 5, as she snapped selfies with her fave stars.

The Sheezus music-maker, who named her third album as an homage to Kanye West's Yeezus, wasn't sure what the reaction would be when she came face-to-face with her musical hero.

Luckily for Allen, the "Stronger" rapper seemed to have taken her adulation in stride, and cozied up to her for a quick picture.

Not to be outdone in the duckface selfie stakes, his fiancee Kim Kardashian also got in on the act, joining the "Hard Out Here" singer, 29, in a girlie selfie afterwards.

Allen looked stunning in a full-length grey ribbon-style gown, and began her slew of selfies en route to the gala in her limo, snuggling up with her date for the night, fashion writer and pal Derek Blasberg.

Later on in the evening, Allen snapped fan pics of Donatella Versace, ASAP Rocky, Rita Ora and Taylor Swift.

But as the elegant evening continued her cheeky selfies got more playful. Taking a trip to the ladies' room with Cara Delevingne, the duo decided to make the most of the baby changing table: Allen convinced the model to jump up and make like she was ready for a diaper change!

Finally, once the evening was over, it was back in the car for the journey to bed. Allen's final snap? The slice of pizza she was about to nosh!
