Well heeled: Nadine Coyle steps out in London today in towering peep toes

Girls Aloud star Nadine Coyle proved she has a head for heights during an outing in London today.

The singer managed quite the balancing act as she left her home in vertiginous six inch peep toe heels.

While her killer heels were distinctly glamorous, the rest of her outfit - rolled up jeans and a loose top fitting top - were surprisingly casual.

Nadine is said to be in the throes of a brand new romance with New York Giants NFL star Jason Bell.

The 23-year-old took her new man out in London last week to meet Nicola Roberts and Sarah Harding, according to reports.

They all headed to Shoreditch House club for a quiet drink together, with her fellow band mates giving the athlete the thumbs up.

Nadine is said to have kept in touch with the strapping American after meeting him in the States earlier this year.

A source close to Nadine has been quoted as saying: 'It's a bit early to call him her boyfriend but the fact she's introduced him to her best friends shows she's keen on him.'

Nadine has been single since splitting with Desperate Housewives star Jesse Metcalfe, 29, earlier this year.
