London, June 19 (IANS) Australian cricketer Shane Warne says his ex-wife should refrain from criticising his fiance, actress Elizabeth Hurley for letting their kids call the latter "Mummy two".
Last month, Warne's ex Simone Callahan, said it was "disrespectful" that Hurley, 47, should have such a nickname.
Now, the cricketer has shot back, saying it is time for Simone to "let it go", reports thesun.co.uk.
"This was something fun between my children and Elizabeth. She didn't ask them to call her M2, it's just something that came up," said Warne.
Warne has three kids - Brooke, 14, Summer, nine, and 13-year-old Jackson.
