Lady GaGa mistook Ed Sheeran for a waiter at the Grammy Awards.

The 'Thinking Out Loud' hitmaker - who was nominated for three awards and also performed at the ceremony at Los Angeles' Staples Centre last night (08.02.15) - has resolved to buy some new clothes after the 'Applause' singer thought he was a member of staff at the glitzy event.

In a tweet which has since been deleted, he wrote: ''I love @ladygaga. Spoke to her earlier and she mistook me for a waiter. Gotta love the #GRAMMYs. #INeedANewSuit? Aha (sic)''.

While Gaga may not be familiar with Ed, she is a big fan of another British singer, Sam Smith, and was thrilled to see him scoop four Grammies last night.

She tweeted: I'm so proud of my darling SAM SMITH for all his wins tonight! You deserve everything and more because you are YOU. I was honored to watch! (sic)''

Gaga herself picked up the prize for Traditional Pop Vocal Album for 'Cheek to Cheek', her collaboration with veteran crooner Tony Bennett - who she also performed with - and was stunned to win.

She tweeted: ''We WON! @itstonybennett & I are so grateful to win this Grammy together! Thank you to our fans! Benedettos, lil' monsters & @theGrammys

''I can't believe it WOW this is my 6th Grammy!! I could never do this without amazing fans, always stay true to yourself I love you so much! (sic)''
