Lucy Mecklenburgh bikini body on Spanish holiday

She was spotted at bootcamp in Ibiza last month where she tried to lose weight with a series of intense exercise regimes.

And it seems Lucy Mecklenburgh's time at the No. 1 Bootcamp certainly paid off, judging by pictures of the 19-year-old star on holiday in Costa del Sol, Spain earlier this week.

The Only Way Is Essex star showed off her enviable bikini body in a pretty pink triangle bikini as she enjoyed the sunshine alongside boyfriend Mario Falcone.

The pair certainly made an attractive couple, as Mario also left people jealous with his muscly physique, which he displayed in a pair of bright yellow swimming shorts.

Lucy teamed her two-piece with a pair of tan wedges and some tiny denim shorts, which she later removed to ensure an even all-over tan.

And Mario certainly appeared to be enjoying the view, helping Lucy adjust her bikini bottoms as she readjusted herself on the sunlounger.

Mario also ensured his girlfriend was well-hydrated during their holiday, bringing her bottles of water and cocktails as they basked in the sunshine.

Later in the afternoon, the pair indulged in a kiss and cuddle before they headed out for the evening.

Lucy, who is a size eight and weights nine stone, previously revealed the reason she went to bootcamp was because all the Only Way Is Essex cast members have been putting in extra effort getting into shape for the new series.
