The 36-year-old actress even matched her T-shirt to her new inking as she left a cafe in Hollywood after having a drink with friends.
Wearing skinny jeans, a loose top and a panama hat, Penelope was dressed for the hot Los Angeles weather, with the new tattoo acting as an interesting accessory to her outfit.
But the meaning behind the new inking is not clear.
The actress is no stranger to tattoos, and has the number ‘883’ etched on to her ankle.
However, Penelope has always kept quiet on the reasons behind the tattoo choice, dismissing rumours that it has links to Scientology or Numerology.

She said: ‘It’s not a Harley Davidson. It’s not the different things that
have been said. I don’t think anyone cares. It’s my own tattoo.’
Penelope previously revealed that her lucky numbers are the numbers 8 and 3, but has not explained why she chose to have the second 8 added.
Meanwhile, Penelope’s relationship with fellow actor Javier Bardem, 41, is going from strength to strength.
Despite the couple preferring to keep details of their relationship private, Javier made a public declaration of his love for Penelope last month as he collected his Best Actor award at the Cannes Film Festival.
After accepting the trophy, Javier told the audience: ‘I share this joy with my friend, my companion, my love: Penelope: I owe you a lot and I love you so much.’
And it seems the dedication was entirely unplanned, as Penelope looked as surprised as the rest of the crowd – her eyes filling up with tears as she heard Javier’s words.
Javier’s dedication has sparked rumours the couple, who have been dating since 2007, are planning to marry in the near future.
