This Morning's Phillip Schofield shocked a guest with an explicit remark on today's show.
The presenter was fronting Tuesday's edition of ITV's flagship daytime programme alongside Rochelle Humes while usual co-host Holly Willoughby takes two weeks off to film a new show.
The two were joined by Vanessa Feltz for a call in segment on the latest show where viewers spoke about disputes they've had with their mother-in-laws.

A caller named Jo detailed her strained relationship with her mother-in-law, before she described the relative as a "pain in the a**e".
Phil and Rochelle erupted in hysterics after the comment and the 59-year-old broadcaster proceeded to repeat the remark twice.
Agony Aunt Vanessa was shocked by the comment - and questioned if it was allowed.
She said: "How many times can we say the A word?"
Phil admitted it was against the rules, before offering an apology.
He joked: "We're not allowed and I haven't even apologised yet. Sorry."
Rochelle added: "Soz, not soz."
Viewers on Twitter were in stitches after the exchange.
Mariam said: "Sheesh barely said what the problem was then says a**e!"
Christoper added: ""My mother-in-law is a pain in the a**e" least she's honest"
@MissLionHeart commented: "Stop the presses! A caller said a**e live on TV!"
Victoria posted : "She said a**e on tv"
Sue tweeted: "Hahaha pain in the a**e"
