While she was seen smiling in some pictures, others show her shouting after promising to make "a lot of noise".
She recently shared a picture of her walking her dogs as she revealed it was her "happy place" following her split.
She wrote: "It is with sadness that I bring you the news that James and I have separated.
"I will be keeping all the dogs with me. I won't be taking calls on the matter as I'd like to be left alone. I thank you in advance for your sensitivity on this subject..."
A description for the protest on Facebook read: "The Environment, Food and Rural Affairs Sub-Committee are investigating the sale of dogs as part of their animal welfare inquiry.
"To encourage the members of the sub-committee to seriously consider the evidence put to them we will be staging a peaceful, non confrontational protest outside Parliament."
