The star took the snap and posted it on her Instagram page and quoted Beyonce with the caption: ‘If @innout burger did a bikini , oh wait #cantkeepyoureyesoffmyfatty.’
The outspoken star shared several other snaps from her America trip, including a selfie of her in a helicopter.
Lily posted the amazing photo alongside some selfies of her in the desert looking make-up free and flawless.
It looks like Lily was enjoying a much -needed day off from her hectic work schedule as she prepares for the release of her new album, Sheezus.
The pop star returned to music last year after taking a break from showbiz to have a family.
The 28-year-old married husband Sam Cooper 2011 and the couple welcomed their first daughter Ethel Mary in November that year. Lily gave birth to Ethel’s younger sister Marnie Rose in January last year.
Lily recently became involved in a Twitter war with rent-a-gob Katie Hopkins when the Apprentice star said the singer ‘gained 2 stone’ and looked ‘pretty horrendous.’
Looks like Lily’s proving Katie wrong!
