The loved up pair, who have been dating for ten months, have not been shy of showing their affections on social media and in pictures.
Former glamour model Katie, 42, and car dealer turned Love Island star Carl, 32 had known of one another for several years but were reportedly put together by a friend over lockdown.
Following Katie’s official divorce from third husband and ex-stripper Kieran Hayler, 34, last month, she has been free to make plans with Carl.
The couple are now reportedly engaged but waiting to share the happy news following securing a five-figure deal with a magazine.
The Sun reports the couple have already posed for a big photoshoot in which the happy news will be unveiled.
A source said: “Katie is madly in love with Carl and excited to take the next step in their relationship.
“But — ever the businesswoman — she knows this is also an opportunity to pick up an easy pay cheque. Katie won’t confirm the news until the cash is in the bank.
“Katie has been down this road many times before but she has no reservations about taking the plunge with Carl.”
The insider added that the former Page 3 icon thinks Carl is “the one.”
