The material irritates the breast lining, creating a serum which enlarges the breasts, a process which could continue indefinitely.

Back in 2011, she said they were growing at a rate of one inch a month.

She did say at the time she would eventually have her breasts reduced and the polypropylene removed, but hasn’t yet given any further updates.

Talking about her procedure at the time to Holly and Phil, Chelsea, who is originally from Minneapolis, said: “Most of the other girls who have had this procedure have stopped at some point so I’m just waiting for that to happen.”

She told the pair that she called her boobs ‘Itsy and Bitsy’ and helped her make a “comfortable living as an exotic dancer and porn star”.

However it wasn’t all plain sailing as she revealed she had trouble eating and has to sleep on her back.

Chelsea also says she struggles to fit into aeroplane toilets and has to perform regular exercises to be able to support the breasts, which each weigh about the same as two large watermelons.

Daytime viewers were left gobsmacked by her appearance at the time and thought the exotic dancer and stripper was more suited to a late night post-watershed show.

One person wrote on Twitter at the time: “Just seen Chelsea Charms on This Morning…WHY?’

However, some viewers were entertained.

Phillip Scofield also posted up a picture of himself with Chelsea after the interview and said simply: ‘Good grief!!

“The lady with the mahooooosive boobs has arrived! Everyone trying to keep their eyes up …. and failing.”
