Jennifer was marvelling at how quickly her adorable Labrador puppy, Lord Chesterfield, was growing up and posted a throwback of herself with him when she first brought him home.

She then added another of him today, to show how big he has got.
The actress welcomed the little fluff ball back in October 2020 and celebrated her new family member with a short video which she posted on Instagram.
At the time she wrote: "Hi! I’d like to introduce to you the newest member of our [paws emoji] family… This is (a very tired) Lord Chesterfield [heart emoji]. He stole my heart immediately.

"A HUGE thank you to @wagmorpets for the incredible work you do. Grateful you take such great care of these rescues and find them their forever homes."
Jennifer also has two older dogs, Schnauzer mix Clyde and black and white pit bull Sophie, and they've all become stars of her social media.
The Morning Show star calls her pets, her "family," and told Dog Monthly she was devastated when her late pet passed away.

"I had a dog, Norman, who was so lovely and was my best friend for many years. When he went at the age of 15 I was heartbroken and I had his name tattooed on my right foot, so he still comes for walks with me."
The beloved dogs share her stunning $25million home with her. The Beverly Hills property has more than enough room for the pooches to run around outside - and inside too!
