It may be more than 20 years since she first got a taste of fame with band No Doubt, but time looked to have stood still for Gwen Stefani as she performed with the band tonight.

The 42-year-old singer took to the stage with her band No Doubt showing off a perfectly toned arms and washboard stomach, reminiscent of her younger years with the band.

Gwen put in an energetic performance with her band at the NFL Opening Kickoff concert at the Rockefeller Centre in New York City.

Gwen's black crop top and black and white tartan trousers showed off her ripped midriff to the maximum, while knee-length black lace up boots provided a sexy touch.

The star enthusiastically sang No Doubt's comeback hit Settle Down with her platinum blonde hair pulled up and wearing her trademark red lipstick.

At one point she threw on a long sleeveless red tartan hood as she played to the crowd.

The star's appearance today was reminiscent of her appearances in the mid 1990s when the ska-pop band had a big hit with Don't Speak.

Gwen regularly sported a series of crop-tops for on stage performances, displaying an equally toned frame.

No Doubt performed at the special concert today alongside Mariah Carey who sang a few numbers – one alongside Cee-Lo Green.

Earlier the singer and fashion designer had covered up her stomach, but onlookers still got a glimpse of her svelte figure as she left her hotel in a see-through top.

Teamed with baggy white trousers, a black jacket and heels, Gwen happily signed autographs for waiting fans before heading to the concert.

Gwen and No Doubt have reunited after an 11-year-break, during which the singer launched a solo career, fashion line, and had two children by rocker husband Gavin Rossdale.

'I don't think [parenthood has] mellowed us out, but priorities have to change,' the singer recently told New York Magazine's Vulture.

'Before, it was unspoken that the band was the No.1 thing; there was not a girlfriend or someone else that could be before the band.

'It wasn't even something we discussed, it just was what it was. But we're at a stage where we don't have to be like that anymore; we can kind of do this when we want to do it.'

However, she said she welcomed the break the band gives her.

'Like today, for instance, I told them, 'I cannot do twelve-hour days anymore, stop it!' she explained. 'I just missed Kingston and Zuma going to sleep. But I get to talk to you, and it's actually a nice break – my kids are so much work. No Spider-Man for me tonight, but that's okay. I'll take a break.'

No Doubt will release their sixth studio album Push and Shove on September 25.
