One Direction cutie Niall Horan appears to have spent New Year's Eve with model Barbara Palvin, who was previously linked to Justin Bieber. There's video to prove that there was holiday hang time between the 1Der and the beautiful babe.

Rumors that Niall and Babs – Niallra? Barball? – were dating began to bubble up last year. Now that they've spent such a big holiday together, we wonder how serious things are between the two.

Horan and Palvin reportedly double dated with Liam Payne and Sophia Smith, taking in Gary Barlow's New Year's Eve concert. Aw! A 1D double date!

You can see Niall and Barbara, both 20, at the show at the 2:48 mark.

Is Harry Styles now the only officially single member of 1D? Are Directioner hearts breaking wide open?

They may be…

If anything, Babs has great taste in tunes and the boys who make them. She's a Belieber and a Directioner.

We hope Niall had a fun NYE, what, with knee surgery on the horizon.
