DAVID Beckham is suing actor Mark Wahlberg after a fitness brand deal soured — leaving him £8.5million out of pocket.

His firm, DB Ventures Ltd, is claiming the Hollywood star “duped” the England footie legend into working with F45.

Becks, 48, agreed to be the firm’s global ambassador when he moved to LA, where he and Wahlberg, 52, became friends.

He is also suing the actor’s firm, Mark Wahlberg Investment Group (MWIG), and gym group F45’s founders Adam Gilchrist and Rob Deutsch.

He claims he lost more than £8.5million when stocks he was promised were withheld until after share prices plummeted.

Wahlberg and his co-defendants claim the allegations of “fraudulent conduct” are baseless and have asked a judge to dismiss the lawsuit.
