Rita Ora has confirmed she is the new face of Madonna's fashion label.

The British singer has officially signed on to front campaigns for the pop icon's Material Girl teenage fashion line, which she co-designs with her daughter Lourdes.

Revealing the news on Instagram, Rita wrote: ''Joining forces with Madonna & Lola [Lourdes]! It's Official Ritabots - I'm the new face of@MaterialGirl. #thisisamoment for me #icon #mymuse #argghhhhh #yeeeeaaahhhhhhh #excited :) :) :) (sic)''

The 22-year-old beauty - who is also the face of Italian shoe brand Superga - was rumoured to have signed a £500,000 deal with Material Girl last month upon recommendation from 16 year old Lourdes.

A source said at the time: ''Lourdes has been a fan of Rita for a while and has been to many of her gigs. She persuaded her mum to see her.

''They met at the Met Ball in New York last week and Madonna admired Rita's attitude so signed the idea off.''

Rita will replace model Georgia May Jagger, who is the daughter of Rolling Stones star Sir Mick Jagger and veteran model Jerry Hall, as the face of the brand.

'Gossip Girl' actress Taylor Momsen has also starred in ad campaigns for Material Girl in the past.
