English actress Kelly Osbourne, known best for hosting the reality series Fashion Police, has announced that she is expecting her first child with her boyfriend Sid Wilson. The 37-year-old shared the news on social media on Thursday that she and the Slipknot rocker partner are set to become parents. Osbourne, who posted a picture of herself holding an ultrasound photo, wrote in the caption: "I know that I have been very quiet these past few months so I thought I would share with you all as to why… I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it. I am ecstatic!" Check out her post below:

Osbourne and Wilson have known each other since 1999 when they first met, but only became close during Ozzfest, a musical event created by her father and legendary rocker Ozzy and mother Sharon Osbourne. A source close to the couple spoke to PEOPLE back in January and said, "They have remained friends since [first meeting]. They are very happy together." Earlier this Valentine's Day, Kelly shared words of love for Wilson calling him her closest friend and "soulmate," while also stating, "I am so deeply in love with you Sidney." Last year, Osbourne mentioned about how keen she wanted to have children but added that her addiction in the past had put a dent to such life experiences with the passing of time. She further divulged in April 2021 that she had relapsed after nearly four years of sobriety. She wrote on her Instagram Story at the time, "This is a little hard for me to talk about, but I've always promised you that I will always be honest with you about where I'm at and what's going on in my road to recovery. I relapsed. Not proud of it, but I am back on track."
