Geri Halliwell Splits From Boyfriend

British pop star Geri Halliwell is single again after splitting from her boyfriend, according to a U.K. report.

The former Spice Girls star has been dating online betting tycoon _A_nton Kaszubowski, 38, for four months, but British newspaper The People now reports the couple has separated.

A source tells the publication, "It's over. Geri finished it with him... He wasn't keeping her interested. Geri is incredibly high maintenance and _A_nton found her quite difficult to be with at times but he really fell for her... Geri now wants to concentrate on being a mum and furthering her career as a singer.

"She's quite sad it has all come to an end but realises she had to make the decision to dump him."

The 40-year-old star has previously been linked to singer Robbie Williams, socialite Henry Beckwith and tycoon Evgeny Lebedev.
