MANILA -- There's no question that Nadine Lustre is one of the most striking young actresses in television today. And she proves to be just as stunning while on vacation, as seen in a photo shared by the sister of her boyfriend, "Till I Met You" co-star James Reid.

Lauren Reid, the sister of James, shared on her Instagram a shot of her with Lustre showing off their backsides in bikinis while on break with a couple of other friends at a resort in Nasugbu, Batangas.

She had earlier shared a photo of her with Lustre swimming, writing: "Just a couple of fish in the sea."

Lustre, for her part, posted a photo of her baring her toned midriff, a day before the conclusion of her primetime series with Reid. "Till I Met You" is set to air its finale on Friday.
