The two stars are rival judges/mentors on U.S. talent show The Voice and Aguilera reveals she doesn't like to sit too close to the not-so funky fresh hitmaker.
She tells U.S. chat show host Ellen DeGeneres, "(I'm sitting) between Blake and Cee Lo with his gas over there... That's why I have the fan, you know."
Realising that she may have upset her pal, Aguilera quickly laughed off her comment and added, "I love you Cee Lo. Don't be mad. Everybody knows."
