According to the Daily Mail, this is the first time that the alleged couple have been pictured at the same place.
Defoe was photographed arriving at the Riverside Studios in Hammersmith and Burke was spotted leaving there later wearing a leather jacket, blue jeans and aviator sunglasses.
Earlier in the day, Burke revealed that she was very excited to be appearing on the comedy panel show presented by Keith Lemon. She wrote on Twitter: "So excited 2Be doing Celeb Juice... Gonna be pure jokes! Hope Mr Lemon don't go in on me (sic)."
After filming, she wrote: "Celeb juice was so much fun. Bare banta! Make sure u guys tune in tomorrow night."
Burke and Defoe both attempted to hide from cameras after apparently dining out together in London on March 12.
Defoe recently tweeted his support for the X Factor star's new single 'Elephant', referring to the 23-year-old as "my girl", but she has insisted that they have just "been friends for ages".
