Nadine Coyle has split from her boyfriend

The Girls Aloud beauty has decided to end her relationship with NFL player Jason Bell – who she has been dating since the summer of 2008 – because it wasn't going anywhere.

A friend of the singer – who now lives in Los Angeles - revealed: "Nadine was the one who decided it wasn't working. They were together for two years but there was no marriage on the horizon. It's all very amicable and they will remain friends. But relationships are all about taking steps and making commitments and they weren't moving to the next step."

It doesn't seem Nadine, 25, will have long to dwell on her decision to separate from 32-year-old Jason, because she is completely focused on completing her debut solo LP.

The pal added to the Daly Star newspaper: "Now she's putting all her energies into making her solo album. It will blow people away.

"She's really thrilled with the results. It will prove once and for all what an amazing talent she has."

Nadine's future with Girls Aloud is uncertain at present following reports her bandmates - Sarah Harding, Nicola Roberts, Kimberley Walsh and Cheryl Cole – are planning to reunite without her.

The group have been on a self-imposed hiatus to work on individual projects, but the other four girls are now keen to get back together with or without Nadine.
