Appearing together in the lead-up to Sunday's celebrations, Kelly Osbourne and her beloved mum Sharon decided to open up about their special bond and happily chatted about their relationship.
Eager to praise her famous mum, Kelly gushed: "My mom gave up so much for me and my brother. I can't even put that into words."
Determined to play down her daughter's praise, modest Sharon insisted: "I wouldn't have anything without you guys. When you think about it, I gave up nothing."
Sharon, who gave birth to Kelly at the age of 34, believes her children have had a bigger impact on her life than anything else, saying: "It was hard because I was working, but I say to all mothers who can just be there full-time for their children, it's a blessing. It's the greatest gift anyone could ever have."
The famous pair have come to blows over the years and famously butted heads as Kelly attempted to navigate the spotlight as a teenager, and they admit they still sometimes struggle to accept each other as they are today, with Sharon saying: "I think the hardest thing I have with Kelly is to let her be her."
Rejoicing that her mum finally acknowledged this fact, the irrepressible Kelly joked: "She's never said that out loud before. Best day ever!"
We really love getting an insight into their wonderful relationship!
