Keep your friends close but your enemies closer! Just one day after Us Weekly exclusively broke the news that Simon Cowell is expecting a baby with New York socialite Lauren Silverman, the X Factor creator and judge's ex-fiancee, Mezhgan Hussainy, was spotted paying him a visit Thursday, August 1.

Dressed in white pants and a beige top, the makeup artist -- who has moved on from American Idol and now works with Cowell on X Factor -- was all smiles entering his Beverly Hills home just hours before he was set to appear at the Television Critics Association Press Tour in L.A.

If Hussainy's visit included a pep talk, it seemed to work! At the X Factor TCA panel later that night, the 53-year-old suavely moved on after reporters asked about being a soon-to-be dad.

"Am I missing something?" he joked. "Unfortunately, I have to keep this for the moment private. It's just one of those things. But thank you very much anyway."

Cowell and Hussainy first announced they were engaged in February 2010, but called it quits in January 2012.
