JENNIFER Aniston's mysterious 11 11 tattoo symbolises two important dates in her life, The Sun Online can reveal.

The Hollywood actress, 51, flashed the wrist inking during a new interview with her Friends co-star Lisa Kudrow on Monday.

Although she had the piece of body art etched onto her skin in 2018, she has never fully explained the meaning behind it.

But now, a source close to Jennifer has spilled the beans.

 was born on February 11, 1969, accounting for one of the 11 digits.

The other is in honour of her beloved pet dog Norman, a Welsh corgi-terrier that passed away aged 15 in 2011.

The source tells The Sun Online: "It's her birthday - 11 February - and the year that Norman her dog died - 2011.

"She misses Norman every day, he truly was the love of her life."

The Sun Online has contacted Jen's rep for comment.

Fans of Jennifer will remember Norman, as he accompanied her on many film and TV sets.

Norman was also very much part of the family during Jennifer's marriage to first husband Brad Pitt.

When the couple split in 2005, she took comfort in her pooch as she came to terms with her heartbreak.

Following his death, which was due to old age, Jennifer paid homage to Norman with a tattoo on her foot.

Bolder than the 11 11 design, Jen's tatt is on the side of her right foot and simply says his name.

Shortly after she'd had the inking done, the A-list star welled up as she confirmed during an interview that it was in memory of her dog.

During the chat with James Lipton for Inside the Actors' Studio, she was also asked what her favourite word is.

Jennifer tearfully replied: "Norman."

Meanwhile, Jennifer had reunited with her former co-star , 56, this week for a new video.

Lisa interviewed Jennifer for Variety's Actors On Actors series and the pair chatted about their time on Friends together.

The pals spoke about the first time they met at the table script read.

Jennifer, who played Rachel Green, told Lisa, who took on the role of Phoebe Buffay, that it was a "woah" moment.

She said: "I'd met Court [Courteney Cox] and known Perry [Matthew Perry] for ever but to hear everybody all together was just like, 'Woahh!'"

Jennifer also admitted to remembering what each of her co-stars was wearing, but couldn't recall her own outfit.
