Kelly Osbourne is pregnant, expecting first child with boyfriend Sid Wilson

Kelly Osbourne announced Thursday that she is pregnant with her and boyfriend Sid Wilson’s first child.

She went on to write, “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!”

The pair confirmed they were dating in February, when Osbourne posted a photo of the two of them to Instagram on Valentine's Day.

“After 23 years of friendship I can’t believe where we have ended up,” the “Fashion Police” alum wrote alongside a February Instagram shot.

Kelly seemed to hint at her own pregnancy at the time, writing, “There is no one more excited for this baby and you know why?

On Instagram, she explained that the pregnancy was why she'd been "quiet" over the past few months.

Alongside Partridge, a host of many other celebrities also flooded Osbourne's comments section with well-wishes.

The music manager said her heart "couldn't be more full" and revealed that she was "so excited to share the beautiful journey" ahead of the younger Osbourne.
