The Skyfall singer - who ditched her usual black attire for a flower-patterned red frock at the bash - was seen proudly sporting an 'A' tatt behind her right ear.
It is rumoured that the 24-year old's son is called Angelo James, leading to reports that she got her new design in honour of him.
As well as unveiling her latest ink, Adele also took home the Grammy for Best Pop Solo Performance for 21 album track, Set Fire To The Rain.
She also hit the headlines today (February 11) after a photo emerged of her appearing to shout at troubled R&B star Chris Brown, after he refused to join a standing ovation for rival Frank Ocean after he picked up his award for Best Urban Contemporary Album.
