Saturday Kitchen host Matt Tebbutt, 44, had to brush over an awkward incident in the first five minutes of the BBC broadcast when the Miranda star forgot to switch her phone onto silent before going on camera.
As the presenter welcomed Sarah, 46, he revealed that her acting career had even included a role as a Bond girl.
“I feel quite guilty, I get quite a lot of mileage out of this,” the blonde beauty laughed. “I was actually.
“My full title was Ocean Sky Receptionist,” she explained, adding that her one scene had featured in Daniel Craig’s second James Bond movie, Quantum of Solace.
“Do you remember the scene where his credit card doesn’t work? I play this frosty woman working behind Ocean Sky’s reception and we share a moment, a little frisson,” she quipped.
However, as Sarah moved on to discuss her current professional ventures, a ring tone suddenly interrupted their conversation.
Hurriedly feeling around her her pockets to put a stop to the offending sound, Sarah’s mouth dropped open in shock and embarrassment.
Matt, however, burst out laughing as she frantically tried to locate her phone.
“Am I about to be ejected from the programme?” she asked as the studio erupted into giggles. “I’m so sorry, I’m so sorry…
“Do I get the feeling that I’m going to get my food hell now,” she asked.
“Do you want to get [your phone]?” Matt joked, as Sarah replied: “No! It’s my boyfriend, he can wait.”
The pair were visibly amused as the actress bravely soldiered on with her explanation about the play in which she is currently starring in, while the Saturday Kitchen host struggled to get his laughter under control.
Saturday Kitchen continues next Saturday at 10am on BBC One.
