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 Anton 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 Anton found her quite difficult to be with at times but he really fell for her... Geri now wants to concentrate on being a mom and furthering her career as a singer.
"She's quite sad it has all come to an end but realizes 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.
