They might have been keeping people guessing on the status of their relationship but actress Kristen Stewart has revealed she has already started talking about kids with her Twilight co-star Robert Pattinson.
The secret came out as the pair desperately tried to dodge a question about their romance on the Oprah Winfrey Show, reports thesun.co.uk.
When the US host asked them whether rumours about their relationship were true, Pattinson joked: "Kristen's pregnant."
Looking uncomfortable, Stewart continued: "He really likes to shock people because he thinks it's funny. We've actually had this conversation..."
Quickly correcting her slip-up and pointing to her stomach, the 20-year-old actress added: "He's having the baby because I can't."
