Hey, whatever happened to going steady?

The news is not much of a surprise to Kelly watchers. C'mon, you know you're out there. The daughter of rocker Ozzy and Sharon Osbourne has actually been wearing a ring on her wedding finger since September.

According to the Daily Mail, Worrall himself let the news out when he changed his Facebook online relationship status to "engaged to Kelly Osbourne."

Yup, that'll do it.

Luke's profile page has now been flooded with congrats from friends and family. 

Relative Nicola Worrall wrote: "I'm pleased for you both xx," while former babysitter Claire Merchant added: "Wow, you've come a long way from the little boy I used to love babysitting for."

According to the DM, Kelly Osbourne recently told the press, "Would I marry him? Yes, you never know. But I'm still really young so we'll have to wait and see. I really do love him, we get on so well."

Is Kelly ready for marriage? Is Luke? Isn't this what they call puppy love?

If so, maybe she should just get another puppy.
