The singer posted this picture on her Instagram page on Monday night.
Her selfie was complete with a straw, a cap and a bit of a strange facial expression...
However, Rita's snap did cause a stir amongst her fans. While some praised her for looking "flawless" others questioned whether she was wearing mascara.
Those lashes do look pretty long, but we reckon it had something to do with her makeup from earlier on in the day.
The singer was spotted wearing her Spongebob sweater dress from Moschino's A/W 2014 collection outside the Radio 1 studios on Monday. Maybe she just forgot to take her eye makeup off? Or perhaps she's a fan of falsies? Either way, well done Rita for doing your bit for charity.
