The X Factor judge, 30, shared a sweet selfie with fans via Instagram on Wednesday (19 March), saying: "Day got cancelled. Spending it with my main squeeze."
Chezza's fans know how much little Chihuahua Buster means to her – she kept him following her divorce from footballer ex-husband Ashley Cole.
In fact, she was famously rumoured to have told Ashley after their split that all she wanted from him was the dogs: Buster and Coco.
In her autobiography, Cheryl talks about how important Buster and Coco are in her life, saying she misses them like "crazy" when she's away. She also reveals how she was with her dogs in 2011 when she realised she was finally happy again following the trauma of her break-up.
And in the past she's even admitted to phoning them up while she's away!
Cheryl's day of relaxation comes following a busy week which saw her confirmed to return to X Factor as a judge for the eleventh series.
She left the UK show in 2010 to join Simon Cowell on the newly-launched US version but, as we all remember, was sacked just a few days into the job, causing a famous rift between her and Simon.
Now, however, they're back on good terms, reuniting on the judging panel for the new X Factor UK series, starting later this year. (Even if Cheryl admits Simon did have to plead very hard to win her back!)
