Nathalia Ramos beach “Brown Bikini” beauty in Santa Monica

For fans of her Nickelodeon show, it would seem Nathalia Ramos has grown up overnight.

But the House of Anubis star looked a far cry from a TV school girl as she took advantage of a filming break to soak in some sun.

The 19-year-old actress showed off her youthful figure in a string bikini to top up her tan on the beach in Santa Monica on Thursday.
