The supermodel, who is best known for walking in the exclusive Victoria's Secret fashion show is newly single after splitting from the Irish One Direction singer just last week.
The pair had been dating for nearly three months but called it quits after their relationship simply 'fizzled out'.
But heartbreak won't keep Barbara at home sobbing into a box of tissues watching rom-coms, she was dressed to impress at the Elle Women of the Year Awards in London last night.
Embracing the hottest trend-of-the-moment, the masculine tailored suit, she was a far cry from the lingerie clad supermodel we're using to seeing on the catwalk.
Although Niall and Barbara have yet to formally comment on their alleged split, the model posted an image of a strapping young fellow kissing her on the cheek Tuesday. The stunning brunette seems to have alluded to the fact she is no longer with Niall, as she captioned the romantic image with the mystery man: “Early Valentine!”
Niall is fast stealing his bandmate Harry Styles' crown as the main lothario of the group, as he has recently been linked to three women - model Barbara, his on/off girlfriend Zoe Whelan and reality TV star Louise Thompson.
And it is claimed Niall is concerned about the reputation he is gaining.
"Niall is pulling his hair out because he just can't make up his mind and feels like he's messing all three girls around," a source explained to British magazine Heat recently.
