Kimberley, 32, and Justin, 31, had their first son, Bobby, on the 4 September so perhaps it's playing happy families that made it the perfect time for a proposal?

According to fine diamond jewellery expert Lewis Malka, this would have been in the region of £20,000.

"Her ring appears to be a yellow sapphire engagement ring of about four carats. The sapphire is surrounded with a selection of yellow diamonds in the same style as Princess Diana's" says Malka.

With a beautiful baby boy and a stunning yellow diamond engagement ring - it looks like Kimberley's Christmas is going to be fairly fabulous.

The star's news comes just a day after she was spotted leaving the Westbury Hotel in London carrying Bobby in a car seat. While she looked every inch the yummy mummy in a little black mesh dress, tights and heels there was no sign of a ring on Friday.

We bet Justin popped the question over breakfast in bed this morning!
