The former Spice Girl is believed to have called time on her two-year relationship with the socialite last week following rows about his love of partying.
According to The Sun, Beckwith, 32, was nowhere to be seen when Geri celebrated her 39th birthday with her sister Natalie on Saturday.
'Geri came to the realisation that things weren't going to work with Henry,” an insider said.
'The age gap meant he had a wandering eye when it came to other women and he was interested in partying. She doesn't trust him. They are still close but Geri is very upset. Natalie has been supporting her.'
Beckwith, who first met the singer in Ibiza, is said to have been reluctant to become a husband, or a stepdad to Halliwell's five-year-old daughter Bluebell, from her previous relationship with film director Sacha Gervasi.
