The 'All Night Long' singer is thrilled the reality TV star is to tie the knot with Joel Madden – with who she has two children with, Harlow, two, and five-month-old Sparrow – and can't wait to perform his father-of-the-bride duties.

Lionel – who legally adopted Nicole when she was nine but had been a dad to her since the age of two – told People magazine: "My happiness for Nicole and Joel knows no boundaries. They have given me two beautiful grandchildren, Harlow and Sparrow, and have proven to be great parents.

"I am not sure who is luckier, Nicole and Joel to have each other, or me, to have both of them in my life. I cannot wait to give away the bride!"

Earlier this week, Nicole confirmed she was getting married when she appeared on 'The Late Show With David Letterman', sporting a large engagement ring.

Good Charlotte singer Joel later confirmed the news - revealing they had managed to keep their engagement secret for some time.

He tweeted: "Yep. I'm engaged. Very happy.

"Yeah we've been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same (sic)."

It has been reported the couple are planning to marry this summer and wedding plans are already well under way.
