Strictly Come Dancing star Amy Dowden was rushed to hospital on Saturday evening after collapsing backstage following the live show.
The Wesh ballroom dancer, 34, who is understood to be in remission after battling breast cancer, returned to the show following a two year absence in September.
But paramedics were called to the show's Hertfordshire base after 9:00pm on Saturday evening following reports of a 'medical emergency.'
A spokesperson for the East of England Ambulance Service said: 'We were called just after 9pm on Saturday to attend a medical emergency at Elstree Studios in Borehamwood.
'An ambulance was sent to the scene. One patient, an adult female, was transported to Barnet Hospital for further care.'

Moments earlier the dancer had performed the Foxtrot to Toploader hit Dancing In The Moonlight with her celebrity partner, JLS star JB Gill.
But fans noted the dancer was partially seated during her latest performance.
The pair climbed to number five on the Strictly leaderboard after being awarded a collective score of 32 from show judges Shirley Ballas, Craig Revel-Horwood, Motsi Mabuse and Anton Du Beke.
A statement from Dowden's spokesperson confirmed: 'Amy was feeling unwell and so an ambulance was called as a precaution.
'She is feeling much better and would like to thank the Strictly family for their love and concern.
'We request Amy's privacy in matters of health is kindly respected.'
Dowden's world came crashing down when she was diagnosed with cancer the day after she came home from her honeymoon with dancer husband Ben Jones in 2023.
While she hoped it could be cured by surgery, two months later in June doctors found another type of cancer.

In what became the toughest year of her life, the professional dancer underwent a mastectomy, chemotherapy, fertility treatment and also almost died of sepsis.
Dowden, who also battles Crohn's disease, confirmed she was cancer-free in February.
While she will not get the all-clear for five years and will still need treatment, she thanked her family and friends for their support amid her 'toughest year'.
Sharing a jubilant picture with Instagram followers, she wrote: 'NO EVIDENCE OF DISEASE! Words I dreamed of! My biggest accomplishment yet!
'I won’t be getting the all clear for 5 years especially with a hormone fed cancer. But it was all worth it. Words I never thought I’d hear at one point.
'So grateful for all the care I received and continue to have.
'To my husband, family and friends who supported me unconditionally and to you guys! Thank you!'
She continued: 'I will still need a monthly injection for 5 years and regular check ups.
'Chemo and this past year has certainly took its toll on my body both physically and mentally, so I’ll be taking the next few months to heal and recover.
'I have so much to strive and live for, and so grateful for another chance at life! Something I know not all get. I certainly see life differently and my life has changed forever!
