Did San Marino's hopeful for the Eurovision Song Contest look a bit familiar?
Viewers on Twitter certainly thought so when they compared semi-finalist singer Serhat to former Celebrity Big Brother star George Galloway.
Other viewers had a different take while they watched Serhat belt out his song I Didn't Know in a maroon suit and fedora but he definitely looked familiar.
The Great British Bake Off's Mel Giedroyc and Radio 1 presenter Scott Mills are co-hosting BBC Four's live coverage of the two semi-finals.
As founders of the competition which was first staged in 1956, the "big five" of France, Germany, Italy, Spain and the UK are automatic finalists, along with the host nation.
The two semi-finals will feature 36 countries, with acts from Cyprus, Azerbaijan, Latvia, Poland, Switzerland, Israel and Australia, to name a few, competing for a chance to perform in the final.
