Gemma Collins believes she "blacked out" during her "Dancing On Ice" performance.
The "Only Way is Essex" star stumbled during her routine with partner Matt Evers on Sunday's (27.01.19) programme and reportedly thinks she fell face-first onto the ice because she momentarily lost consciousness after her blood sugar levels dropped too low.
A source told The Sun newspaper: "Gemma had been wired up to a heart monitor before she went on stage.
"She believes she blacked out while she was skating, which is what caused her to crash into the ice.
"She didn't know what had happened when she got back up -- her blood sugars were low and she didn't feel right."
Gemma is expected to learn later on Tuesday (29.01.19) whether she'll be fit to skate this coming weekend and even if she isn't, she's determined not to quit the competition.
The source added: "She is determined to make the show on Sunday despite the injury and is telling her friends, "I ain't giving up"."
The 37-year-old star has been left in agony with pain in her knees and resorted to using her mother Joan's wheelchair to get around on Monday (28.01.19).
However, Gemma won't let that stop her from fulfilling commitments she already has in place.
The insider said: "Yesterday she was being wheeled about in her mum's wheelchair but still made a commitment to visit a children's hospital because she didn't want to let anyone down."
Gemma had previously admitted she was "absolutely devastated and embarrassed" by the fall but couldn't wait to get back onto the ice.
She wrote on Instagram at the time: "Absolutely devastated & embarrassed. My heart is broken but when I went down I thought of @gypsyking101 Tyson Fury and knew I had to get back up & carry on! Can't thank you enough for your support on social media and picking up the phone to vote! I'm in a lot of pain but bring on fantasy week!! (sic)"
