The name of British singer Lily Allen's baby is out - thanks to her mom! Lilly gave birth to her first child with husband Sam Cooper in November. However, Lily has kept a low-profile since becoming a mother and hasn't released any details about the new arrival. Her daughter's name has been a heavily guarded secret, but NME is reporting that Lily's mother Alison Owen inadvertently revealed her grandchild is called Ethel Mary while posting a message to a pal on Facebook. Last month Lily took to her Twitter account to thank fans for their support following the birth of her baby. 'Thank you for all the flowers and lovely messages everybody. Very touching indeed. nuff luv x x (sic),' she wrote.
