In their first joint public appearance since renewing their wedding vows, the couple looked happy as they posed on the green carpet on Thursday night (26 March).
Katie switched her usual mega glam look for a casual one – well, she was traipsing through a maze tackling I'm A Celeb-themed goodies!
She kept her hair up in a messy topknot.
It was probably a pretty big blast for the past for Katie, who appeared on I'm A Celebrity twice. First in 2004 and then fleetingly in 2009.
Thorpe Park's new maze, which opens to the public today, allows people to step into the shoes of the campmates by competing for stars in iconic trials including Catacombs of Doom and Chambers of Horror. Yikes.
Katie and Kieran left the kids at home.
They're parents to baby Bunny, born in August, and son Jett, who turns two this summer. Katie is also mum to sons Harvey, 12, and Junior, nine, and daughter Princess, seven.
The couple married in January 2013 in a Bahamas beach wedding but renewed their vows in February surrounded by friends and family in West Sussex.
Katie has said the vow renewal was for Kieran's benefit, not for hers, as he needed to recommit to her after breaking their vows by cheating on her with two friends.
