It seems that the world will finally come to understand why 1D member Niall has the hots for the Hungarian model. As if her Victoria Secret stints are not enough, the 1D member's rumored girlfriend posted a few shots of herself in undies.

Barbara Palvin took to Instagram to announce a new campaign for Twin-set Simona Barbieri's lingerie collection. Posting a collage of a few lingerie shots, the Hungarian model captioned the Instagram image, "new Twin-Set lingerie campaign! woopwoop! #twinset @twinsetofficial."

Niall's rumored love interest is seen sporting a pale-pink-with-dark-polka-dots cardi in one shot, seemingly in an attempt to cover up. But judging from the shot, it looks like it'll take more than a cardi to tame down Barbara's curves.

The model is seen in two other floral-inspired outfits in the Instagram post which had followers commenting praises for her svelte body.

A quick trip to the Twin-set Simona Barbieri website reveals even more sultry photos of Niall's rumored love interest. The online lingerie catalogue of the said brand has Barbara Palvin spanned across the page but the VS model is also modeling the brand's other collections.

According to FabFashionFix, Barbara has been chosen as the new face of the brand for its Spring and Summer 2014 campaign. The Italian fashion brand pairs the model with classical slim jeans, lace blouses, boyfriend jeans and hot denim shorts, notes FabFashionFix.

And although it seems that the world and some Directioners are all vocalizing praises for Barbara, Niall has remained mum about the sultry happenings - at least on Twitter.

The 1D member's latest tweet says that he was going on a drive around London. He also called out to Michael Clifford of 5 Seconds of Summer, an Australian pop rock band.

Niall tweeted, "Now we're going on a night time drive around London! see the sights homies! @Michael5SOS went t bed early ! Loser."
