Talking to US Weekly, the talkshow host revealed that she and her 13-year-old adopted daughter Chelsea have watched the programme together and ultimately found that it sends a positive message to young girls.
"I have to say it's interesting. My daughter is 13. I watch it with her," she explained.
"I think the fantasy for adopted children is to have a baby of their own, and then keeping it, which their mother did not do."
O'Donnell also said that she was keen to see the series and decide for herself whether or not it was appropriate viewing for her kids.
"The rate of teenage pregnancy is up, so when my daughter saw that Teen Mum 2 was on the air, I said, 'Let's watch it'.
"At the end of almost every episode the mothers say they wish they used protection or waited, 'My whole life is over', or, 'I can't live the life of a teenager'. I think it sends out a positive message."
Kim Kardashian recently criticised the show, claiming that it teaches teenagers to idolise young mothers.
