One to watch: Eamonn & Ruth's 7-Year Itch, Channel 5
Eamonn Holmes and Ruth Langsford have developed a reputation for their, at times, pantomime-style bickering on TV shows, in particular on This Morning, which they host every Friday and whenever Holly Willoughby and Phillip Schofield are absent.
However, according to the pair, both 57, they are more in love than ever.
After beginning a romance with then-married GMTV star Eamonn in 1997, Ruth first appeared on Loose Women in 1999, and began guest hosting This Morning in 2000.
In 2002, she and Eamonn had a son called Jack, before marrying in 2010 and settling down in Surrey.
The TV couple celebrated their seventh wedding anniversary in June, and as they enter the notorious "seven-year itch", they explore ways to spice up a marriage, meeting couples who have successfully scratched the itch, finding astonishing ways to overcome the most extreme marriage crises.
In this two-part series, Eamonn and Ruth will investigate the myriad ways to add a sprinkle of spice and reignite the spark.
They begin with an alternative sex therapy session, and learn how their instructors believe that their open relationships strengthened their marriage.
The couple then visit a dungeon in central London that caters for couples who take pleasure in fetish and BDSM scenes, allowing them to indulge in activities that might be a little too extreme for the family home.
Eamonn and Ruth also meet married grandparents who get their kicks from outdoor sex and swear that getting back to nature is the perfect tonic for a relationship.
Then, in the glamorous setting of the Rivoli ballroom, with married dancers strutting their stuff, therapist Dr Dance explains how dance can also be a potent force in spicing up relationships - especially the tango. Perhaps that's why Ruth agreed to join Strictly.
Finally, Eamonn and Ruth meet a "sex surrogate", who has a rather hands-on method of getting love lives back on track.
But will this encounter lead to added excitement and adventure for the celeb couple? Or simply add to their bickering?
