New York, June 7 (ANI): Following news last week that former child star Mary-Kate Olsen is dating Olivier Sarkozy, the 42-year-old businessman brother of the former French President, Nicolas, Olivier's ex-wife Charlotte, has spoken out about the pair, branding their relationship as 'grotesque'.

"That's not right. It's grotesque," the Daily Mail quoted her as telling the National Enquirer.

Mary Kate is 17 years Olivier's junior but they are said to be 'head over heels' after being spotted cuddling up to each other at Madison Square Gardens on April 25.

"Charlotte certainly won't want her kids to be around Mary-Kate, who has a history of wild-partying and booze binges," the source said.

Charlotte and Olivier, who have two children together, got married in 1997 and were divorced 13 years later.

He has previously been linked to actress Stella Schabnel, 29. (ANI)
