She was diagnosed with breast cancer almost three years ago and after a tough and private battle with the disease, she was given the all-clear in June 2010.
So it was no surprise to see Jennifer Saunders venture out in the middle of the night to raise money for breast cancer care.
And to prove that she is fighting fit again and has never felt better, she flashed her ample bosom in a pretty Swarovski crystal bra as she took part in last night's MoonWalk in London.
Jennifer, 53, looked ready to tackle the half-marathon walk alongside 17,000 others who were either doing the half-marathon of 13.1miles or the full 26.2mile marathon.
The Absolutely Fabulous star was diagnosed with breast cancer in autumn 2009 and was given the all-clear in the following June but must take Tamoxifen every day for the next four years to reduce the chance of the cancer returning.
She didn't speak publicly about the disease and carried on as normal continuing to appear at public events until she appeared at a fashion show in the July showing her short soft hairstyle, a result of her chemotherapy.
She was in fine form last night and took to her Twitter page repeatedly to update her followers on her progress throughout the walk.
She began by writing: 'Back from France. So little sleep I feel I have jet lag. But ready and excited to walk amongst tits tonight. Full of energy. Bring it on!'
Later she added: 'I'm knackered and I've only just walked to the tent!' and then said: 'Oh lord. Swarovski crystals from bra have migrated into my pants. Will need to stop.'
But she completed the walk and praised fellow actress Miranda Richardson, who has appeared in Ab Fab, for her walk, saying: 'Miss Richardspn was our fastest. Secret is never to stop for pee.
'Miranda completed Moonwalk much faster than the rest of us. She trains with a leaden vest so gravity was less.'
Also doing the walk last night was TV presenter Anthea Turner who was joined by former Page 3 girls Nina Carter and Jilly Johnson as well as Hollyoaks actress Karen Hassan.
Other celebrities taking part included Anneka Rice who wore a MoonWalk T-shirt to the event and Penny Smith who opted to wear her bra over her jacket.
The walk started in Hyde Park and made its way round The Mall, Westminster, Embankment, Vauxhall bridge, Battersea Park and Knightsbridge before finishing with a lap of Hyde Park.
