Guess the blingThis princess-cut sparkler is to die for.

It's simple, but the stone says it all.

But who's the owner of this bit of bling?

She's fresh on the engagement ring block, and between her television hosting duties she looks like she's been shining this baby up a treat.

Step forward Denise Van Outen, who's been seen flashing her newly acquired engagement ring all around town.

This is the fiDenise Van Outenrst time we've clapped eyes on the sparkler, and we must say we're impressed with her fiance Lee Mead's choice.

Lee got down on bended knee last month in the Caribbean island of St. Lucia to ask Den to be his wife.

But what we want to know is, what's with the wedding band? If you look closely in the pic above you can spot a band of diamonds tucked snugly behind it.

Have the sneaky pair gone behind our backs and not invited us to their wedding?

Relax folks, we're happy to tell you it's not the case.

Because Den's been blabbing about her up-coming nuptials, and she says she'll be waiting until after her hotly anticipated Mount Kilimanjaro charity climb for Comic Relief to tie the knot.

"I'm really excited. But there's a lot to organise," she told Closer magazine. "It'll be later this year. I want to get the climb done and then we'll work out what's what."

So it seems that Den's been doing a little bit of practising for the big day... How sweet.
