The 41-year-old radio personality has admitted he was the "lead bridesmaid" for his sibling Meredith's party, which saw him organise a trip for "17 women to Napa", and the star has revealed the "one challenge" he faced was ensuring the full group got ready in time because of the limited bathroom space.

Speaking about his wedding duties and party planning Harry Connick Junior on the 'Harry' daytime television show on Friday (02.12.16), the dark-haired hunk said: "I was the lead bridesmaid. I called my sister and said, 'What does it mean Man of Honour?' and she said, 'Well you've got to do everything a Maid of Honour would do.' I said, 'A bachelorette party?' She said, 'Yeah.' I said, 'Okay.'

"Oh yeah, I had to take 17 women to Napa.

"The challenge -- you'll appreciate this because you have only girls in your house -- the challenge was keeping them on schedule because there were limited bathrooms for 17 women. They did a pretty good job but that was the biggest hurdle was telling them what time they had to be ready and what time reality was."

And the 'American Idol' host has admitted he felt very "emotional" when his younger sister asked him to be her equivalent of a Maid of Honour in October last year.

Speaking about the poem she gave asking him to accept his role, he said: "[She said] 'You've been by my side all of my life, and I wouldn't want you anywhere else, when I become a wife. I'm so lucky to have you as my brother, and couldn't imagine celebrating with any other. So basically what I'm trying to say... Will you be my Man of Honour on my special day?!'

"It was really really cool, so emotional but so proud of my little sister."
