Barbara Palvin Out, Selena Gomez In: One Direction Niall Horan's Alleged New Girlfriend?

One Direction's Niall Horan is turning out to be another ladies' man. After his split from Victoria's Secret model Barbara Palvin late last month, it looks as if he took no time in replacing his brunette beauty with yet another dark-haired lady. Who is it that has allegedly caught Horan's eye? Well, none other than Justin Bieber's ex-girlfriend, Selena Gomez.

Both singers have sparked dating rumours after they were seen at London post-Valentine's Day. Could it be that the two have gone past the "more than friends" zone? If fans may recall, Niall Horan refused to date Selena Gomez in the past due to the fact that she was one of his mates, Justin Bieber's' ex-girlfriend.

"Not only are they friends, but Niall's keen to avoid any trouble with Justin. He knows dating Selena could've prompted a war with Justin," states a source in a report by Hollywood Life.

However, there seems to be a change of heart. The One Direction singer was spotted with the former Disney star in London over the weekend. The two casually posed with fans outside Nando's. Check out the photos here and here.

Of course, only time will tell if there is truly something romantic going on between the two. Fans may also recall Niall Horan was at one of Taylor Swift's concerts that also sparked rumours of them dating. It may seem as Niall is making quite a number of connections with the ex-girlfriends of his best mates.

As for Barbara Palvin, well it's safe to say that she and Niall are over. The Victoria's Secret model took less than no time as well to find her easy replacement for Niall Horan. Before Heart's Day hit the world, she had celebrated early with one cutie. Check the photo here.

"There was no big fall out," says the source to The Sun, adding, "Things just fizzled out as Barbara and Niall are both working in different parts of the world."

Other reports however claim that Niall isn't making the moves on Selena Gomez but on a certain red-head named Helen Flanagan. Check out the photo of Helen here. With one rumour to the next, "Directioners" best hope of the truth is asking Niall Horan directly who his real new girlfriend is.
