The troubled actress will be the chef's celebrity assistant on an upcoming episode of 'Jimmy and Jamie's Friday Night Feast' and was thrilled to be invited onto the Channel 4 programme.

Sharing a picture of herself cooking with Jamie, she wrote on Instagram: "#jamieandjimmysfridaynightfeast #cook with #love with @jamieoliver @jimmysfarm #food #comingsoon #thankyou my friends of the crew and team of #jamieoliver and my team @celinebopp @oliverdrama @royceangeloevents #backtowork #uk #grateful #chef (sic)"

But it seems the 'Mean Girls' star has blown a surprise as she posted her picture shortly after Jamie, 41, teased his "last secret guest".

He shared a picture of himself, co-host Jimmy Doherty, and a "mystery" female in silhouette on Instagram as he thanked those involved with the show and urged fans to guess who he'd been filming with.

He wrote: "That's a wrap guys......As the sun goes down on me , Jimmy @jimmysfarm and our last secret guest on #fridaynightfeasts I'd like to thank everyone who helped make this series,our cafe customers ! our amazing celebrity guests !
