Niall Horan & Allen Leech

Allen Leech, who plays Tom Branson in the period drama “Downton Abbey,” has joked that One Direction’s Niall Horan would be the perfect person to play his son.

The Dublin actor reckons that the Mullingar popstar should make a cameo in the hit show’s fourth series as the blonde pair look quite similar.

Speaking to MTV Leech joked, “You mean, my son? My son Niall Horan. Absolutely, and then we actually do a musical episode and we get the whole of One Direction in."

“I pitched it to Julian (Fellowes, creator and writer). Weirdly enough, he hasn’t gotten back to my email.”

This bunch of One Direction and “Downton Abbey” fans are behind Leech on this one. Make it happen!
