The Wannabe hitmaker was walking her Labrador Retriever in a section of London when the pet unexpectedly took off.
The 37 year old searched desperately for the pooch on her own but to no avail, and now she has asked her online followers to keep an eye out for Phoebe and report any sightings.
In a series of frantic posts, she writes, "My gorgeous brown Labrador went missing on daily walk, she will be so scared please look out around east barnet, Hadley wood, Trent park (areas)... Her name is phoebe!! She is so gentle, please look out for her.
"I'm in bits, thank you for all your reassuring messages! Please keep looking."
