The former Friends star and Hollywood actress has got a real thing for pooches. She's already the proud dog-mum of a Schnauzer called Clyde and a white Pitbull who goes by the name of Sophie.
And the pair now have a new doggy brother after Anniston adopted another puppy from the Wagmor Pet Hotel, an LA-based animal rescue and adoption service. She introduced him to fans via a heartwarming Instagram post, which shows the furry fella munching on a chewy toy while drifting off for a nap.
Love at first sight
Fans couldn't get enough of him, although some made a few comments about his unusual name - Lord Chesterfield! Anniston didn't share her inspiration for picking his hilarious moniker, but she did say it was love at first sight.
"Hi. I'd like to introduce you to the newest member of our family...this is (a very tired) Lord Chesterfield," posted the actress. "He stole my heart immediately!"
The original Lord Chesterfield
And just like his A-lister mum, little Lord Chesterfield has got some famous friends and admirers. Fellow actress Lilly Collins commented on the post, writing, "I actually cannot deal with this cuteness. The name, the pose, everything!"
The original Lord Chesterfield was an 18th Century British statesman with a reputation for being a bit of a scoundrel. So, for Jennifer's sake, let's hope little Lord 'Chestie' doesn't follow in his namesake's paw-steps!
