It might be time to whack out that #CongratsNiallandMelissa trend on Twitter again, because Niall Horan has been spotted leaving a fancy charity bash with rumoured girlfriend Melissa Anne Whitelaw.

Niall, along with bandmates Louis Tomlinson and Liam Payne,cleaned up pretty darn well for Trekstock’s Great Gatsby themed charity event last night (April 16), and while everyone was distracted by the boys in suits, Niall managed to take off into the night with Melissa (and Louis) in tow.

In case you’ve managed to miss all the drama surrounding Niall and this mysterious Melissa so far, the pair have been linked together since last November, when she was spotted with Horanat last year’s ARIA Awards.

Since then, she’s been spotted on the Australian leg of One Direction’s' On The Road Again' tour and even pictured allegedly kissing the Irish boybander.

Melissa, who’s 21 and Australian, has received quite a lot of support from the 1D fandom since the rumours of the apparent relationship started surfacing.

Back in February, #CongratsNiallandMelissa trended worldwide on Twitter, which was probably quite a nice surprise for the potential lovebirds.

Whether they’re dating or not, we just hope Niall’s happy. Although, we’re pretty sure he’d be happiest if he were dating us, but whatever.
