The 'Lip Sync Battle' star - who is expecting her first child with the 36-year-old singer - has vowed her dinner parties will be better than ever after her husband splashed out on a giant "cheese wheel".

Alongside a picture of herself kissing John on the cheek as he held the gift, she wrote on Instagram: "John got me my lifetime dream for Christmas.

"A cheese wheel to dump pasta and risotto in for years to come! My tableside serving game is bout to be liiiiiit! Heading out to relax with the fam now woohoo!"

She later posted another picture of the wheel in action.

She wrote: "If you haven't seen one of these wheels in action oh man, it is a thing a beauty. Hot pasta is tossed around, gently melting the cheese and plated right at your table. It makes me emotional (sic)"

John recently described Chrissy, 30, as the "head chef" in their household.

He said: "She's the head chef but I'm her sous chef. And I'm in charge of breakfast usually as well."

And the 'All of Me' hitmaker previously praised his wife for being a "great cook".

He said: "When she's working on it and I'm home I gain five pounds guaranteed. So, I'm like, sometimes I need to travel so I can lose weight!

"[Her best creation] is kind of like when people do those artichoke dips but it's got buffalo chicken and cheese and all these other things in it, too. It's really, really delicious. Chrissy is obviously a great cook."
