Gwen Stefani wows the crowd as she reunites with No Doubt to perform at the New Orleans Jazz Fest

Gwen Stefani reunited with No Doubt to play the New Orleans Jazz Fest and all she had to say about it afterwards on social media was 'Wow.'

The singer shared a photo of her and bassist Tony Kanal playing live on stage right after the gig ended, adding the hashtags #Nola #rad #blessing.

The 45-year-old mom-of-three seemed to roll back the years as she fronted the rock band that made her famous.

The stunning rocker wore a funky outfit of a sleeveless denim vest with red embroidery, and multi-colored short shorts over fishnet tights.

Gwen accessorised knee-high laced black boots and a bright yellow and colorfully patterned shirt tied around her waist.

But her biggest accessory was her very long platinum blonde ponytail that she flipped with gusto during the set.

She completed the whole look with her signature scarlet red lipstick and plenty of gold bracelets and rings. 

Bassist Tony Kanal, who had a relationship with Gwen when No Doubt first started out, also had his short hair dyed his trademark blonde hand wore a sleeveless t-shirt and camouflage pants as he gave the performance his all.

The rare reunion is one of several gigs the band are doing together.
