According to In Touch magazine, 'multiple sources' have confirmed that Tom Cruise's ex-wife is romantically involved with his close friend.
“Katie and Jamie have been dating for a while,” an insider told the US mag. “They’re very Mission: Impossible about their romance.”
A second source confirmed to In Touch that one morning in September, a driver arrived to collect Jamie, 45, from the Trump Soho Hotel to take him to the set of his new film, 'Annie' — but Katie stepped into the limo instead.
Katie was first spotted partying with Jamie in July at the star-studded Night Of Legends party in the Hamptons.
Another partygoer said Katie - who divorced Tom in 2012 after six years of marriage - began dancing with Jamie when Lenny Kravitz took to the stage and was also reportedly seen sharing his drink.
However, a rep for the 34-year-old actress insisted the pair are still just 'friends'.
