By day she is a doting mother of two.

But Gwen Stefani turned on the glamour on Wednesday as she headed out for a night in London.

The singer, who turns 43 next week, looked fantastic in an optical illusion metallic dress, which she teamed with a pair of racy footless tights.

Gwen, who is currently on a promotional blitz for No Doubt's sixth studio album Push And Shove, was snapped arriving back at her hotel.

She wore her blonde hair in a side parting, swept over to the side, complete with dramatic eye make-up and a splash of pink lipstick.

In a new interview, No Doubt say they feel every song on their new album is 'pretty awesome'.

Guitarist Tom Dumont - who is joined in the band by Gwen Stefani, Tony Kamal and Adrian Young - admits the new LP 'Push and Shove' is not the kind of work where you have to skip past filler tracks as he thinks they are all very good.

He said: 'I love all the songs on the album, and I think for me, personally, I love albums the most where you don't have to forward past filler, and I don't want to presume to make that judgment on our album, but for me, I feel like every song is pretty awesome.'

However, he is particularly enamoured with the final song on the album because it has a feeling of a 'prom' theme.

He told MTV.com: 'The last song on the album is called Dreaming the Same Dream, and as we were writing it, we were trying to do this prom song, and there's just something about it that I love.

'It has this amazing ending that ends the album really powerfully. Right now, that's my jam.'

The band have been carefully working on their new material since reuniting in 2008 - after taking a hiatus in 2004.

During their break, Gwen enjoyed worldwide solo success and launched her own fashion lines - L.A.M.B. and Harajuku Lovers.
