Geri Halliwell was left "fuming" when she caught her boyfriend gazing at another woman.
The former Spice Girls singer was on a romantic holiday in St. Tropez, France with her lover Henry Beckwith - who she has been dating since March 2009 - when they started rowing after she caught him staring at a young brunette in a bikini top and tiny white shorts.
A source told Mail Online: "Geri was absolutely fuming. She was shouting at him and telling him what for. Clearly, she was not happy about his wandering eye. As soon as she clocked him, she turned around herself to see what he was looking at and then she twigged."
The pair had been strolling hand-in-hand along the seafront when Henry got distracted, stopped walking and turned around to get a better view of the woman.
The 37-year-old singer reportedly started screaming at him, throwing her arms in the air and pushed at his chest in anger.
A passer-by even approached the couple to make sure everything was OK.
After their feud, Geri and Henry cut their evening short and quickly jumped in a dinghy which took them back to their yacht.
