David's Final Betrayal-Posh Walks Out!

She’s livid at Becks’ hot-tub frolic with Courteney Cox...

Their trip to LA was intended to provide some much-needed relationship R&R – but David Beckham went and put even more strain on his already-rocky marriage to Victoria by hopping in a hot tub with Courteney Cox!

Mounting tension between the Beckhams reached fever pitch when Courteney, 55, posted bikini-clad selfies in a spa with David, 44, while they were shooting cameos for Modern Family.

However, while it was clear the new co-stars were having a ball together, furious Posh is about to bust David’s golden ones!

Yep, when the designer, 45, saw Courteney’s hands all over her husband’s half naked body, she lost the plot and walked out following a heated row with Becks.
