The two lesbians have been romantically linked recently following the actress and TV presenter's split from her wife Michelle Rounds, but Hawkins insists she and O'Donnell are just old friends.
Responding to the new romance reports, the singer says, "I am not romantically involved with Rosie or anybody for that matter. Rosie has been a dear friend for 30 years. I am very proud and happy to be having this child on my own."
Hawkins announced she was pregnant with her second child in February (15) - the same month O'Donnell filed for divorce from Rounds after nearly three years of marriage.
