The real-life romance of Twilight stars Kristen Stewart and Rob Pattinson is in turmoil after she told to a friend she believes she is pregnant with the actors child

The actress, who discovered she could be expecting last week, was so worried someone would discover her secret she sent a close pal to buy a pregnancy test kit.

“Kristen asked one of her friends to buy the test because she was worried about someone seeing her at the drug store,” an insider reveals exclusively to NW. “She’s very nervous about the whole situation.”The couple, who haven’t even gone public with their romance yet, are now facing the toughest challenge to their relationship as they struggle with the news they could be parents.

Kristen first started to suspect she might be expecting when she realized she hadn’t had her period.

“When she worked out she was late, she obviously started to thinking that she could be pregnant” says a pal. “And because of the timing, she thinks Rob could be the father.”

HONESTLY, I think its bullshit!
