Who would know Niall better than his 1D bandmates? His brother!

Luckily Greg had no problem spilling all the tidbits about how his bro figures out who is potential girlfriend material.

“They [One Direction] test girls out to make sure they are trustworthy,”

“Niall will follow you on Twitter for a while and suss you out, make sure you’re genuine and have you out — then go for it.

Greg thinks that Niall is a true ladies man, and admits to asking him for advice.

He says that Niall has figured out the perfect way to a girls heart, “It’s not full on straight away. He’ll maybe go for coffee. They are all quite innocent. It's always better to take it slow, and going for coffee is a good way to start!

What do you think of Niall's way of approaching girls on twitter?

Would you be mad if one of your siblings dished about your romantic life?

UPDATE: Greg Horan officially denied this on Twitter.
