The stunning model and TV presenter, who is married to Tottenham star Rafael, was spotted soaking up the sun at the La Sala Beach Club.
Sylvie showed off her incredible bikini body, which is toned, trim and flawless for her 34 years.
Life of luxury: The WAG, model and TV presenter reclined on a sun bed and read magazines at the La Sala Beach Club
The Dutch beauty reclined on a sun bed, reading magazines and chatting on her phone.
She got up and went for a dip in the pool, turning heads with her long limbs and flat stomach clad in a bright blue bikini.
Sylvie cooled off in the water, resting by the side of the pool as she soaked up the suns rays.
She was joined by husband Rafael, 29, who took a dip with his gorgeous wife and was seen giving her a kiss back at their sun bed.
At five years her husband's senior, Sylvie easily rivalled him for best beach body.
The couple are holidaying in Marbella with their six-year-old son Damián.
Sylvie posted a picture of the family on the beach on Twitter yesterday, writing: 'Played some football on the beach today with my 2 men..love being active during holidays.'
The family are vacationing after Sylvie made a heralded return to the catwalk last week at Berlin Fashion Week.
The comeback was especially sweet, given that her hiatus from modelling was caused by Sylvie's breast cancer diagnosis in 2009.
Walking for lingerie brand Hunkemolle, she posed in a black feathered underwear set studded with diamonds.
After finding a lump in her breast in 2009, Sylvie underwent surgery and a gruelling six months of post-operation chemotherapy which saw her lose her famous blonde locks.
After having her head shaved, the mother-of-one wore wigs until husband Rafael persuaded her to go natural while appearing on the German version of Let's Dance.
