It seems like One Direction's Niall Horan isn't all grown up judging by this snap.
The Saturdays' Rochelle Humes posted this cheeky picture of herself and hubby Marvin feeding an baby-faced Niall.
She captioned the pic, "@MarvinHumes and I doing the night feed ;) @niallofficial."
Niall posed for the picture as Rochelle fed him with one of her daughters bottles while Marvin stroked his head.
Aww, now that's what we call love.
The boy band singer tweeted, "Really good laugh last night with @RochelleTheSats and @MarvinHumes, finally got around before Alaia-Mai 's bedtime and met the little cutie."
The 19-year-old jetted in from the US yesterday (13 August) as he's taking a break from his hectic tour schedule and went to visit the couple's newborn, Alaia-Mai.
