Luisana thinks One Direction's Niall would make a good dad

Michael Bublé‘s wife Luisana Lopilato has been joking with Niall Horan on Twitter about the paternity of her unborn child.

The Argentinian model revealed she was pregnant with Michael‘s baby last week – but it seems she would rather have conceived with One Direction‘s Niall, 19.

‘@NiallOfficial I wish that you could have been the father !! Hahah I went the “wrong direction” @michaelbuble says you can be the stepdad,’ Tweeted Luisana, 25.

Niall replied: ‘@lulopilato hahhahahaha! Thanks mike! Much appreciated haha! And Lu it would be an honour !’

Niall isn’t the only member of 1D who Luisana has invited to become a family member to her and Michael‘s little boy or girl.

She told Liam Payne, 19, that he’ll be considered an uncle to Bublé Jr after he congratulated the couple on their big news.

‘@Real_Liam_Payne you will be the sexiest uncle the world has ever seen!!! Hahaha,’ Tweeted Luisana.
