Harry Judd has been "floating in a cloud of love" since becoming a father.
The McFly drummer and wife Izzy - who he married in 2012 - welcomed daughter Lola Rose Emma into the world late last month after undergoing fertility treatment and the couple couldn't be happier.
Harry said: "Everything we went through was worth it because it has brought us to this moment. IVF is just mind-blowing and such an amazing thing to give us this family.
"You are just floating in a cloud of love. Our wedding day was the best day of my life and this was a similar feeling, but times 10.
"Being a dad just feels right. It feels quite natural. It is the best thing ever."
Following their struggles to conceive, violinist Izzy admits it was a "relief" when her daughter was born healthy.
She said: "It's such a relief when you hear her cry and know she's OK.
"We first saw Lola as an embryo on a screen. All babies are miracles, but she fought the race."
And seeing his wife give birth has changed the 30-year-old musician's view of his spouse forever.
He told Britain's HELLO! magazine: "I've never been so in love and proud of Izzy. To see your wife going through all that for the greater good, doing it for us and our family, it's just incredible."
