After his highly-publicized break-up with fellow 'Twilight' star Kristen Stewart, Robert Pattinson has been rumored to be romantically involved with singer FKA Twigs, whose real name is Tahliah Barnett. On that note, Pattinson's alleged girlfriend recently sparked pregnancy rumors by means of her statement over Twitter.

The statement FKA Twigs posted on her official Twitter page caused a frenzy from fans of her music, and even fans of the English actor Pattinson.

"i've a baby inside, but i won't give birth till you insert yourself inside of me," read the singer's Tweet on Sept. 15.

Although no one knows if the singer is actually claiming that she is with child or she just posted song lyrics, Barnett's tweet still caused rumors of her pregnancy to spread on the Internet.

A source close to the 'Remember Me' actor, however, claims that the pregnancy rumors are not true.

"Rob has not got anyone pregnant. Whatever that tweet or rumor is about is basically just that, a big rumor!" the source told Hollywood Life.

Stepping beyond the pregnancy rumors, fans are still trying to figure out what Barnett's tweet could have meant.

Some websites claim that Barnett's tweet could just be the lyrics of a new song or an idea for a new composition, while some claim that the singer could only be playing with people who are crazy over Pattinson.

Pattinson and Barnett were first rumored to be dating each other in September, and were spotted strolling together several times. The two were allegedly introduced to each other by a mutual friend.

Pattinson has been linked with several women, including Dylan Penn and Riley Keough, but Barnett seems to be Pattinson's first girlfriend since his controversial break-up with Stewart.

It is still unclear how serious Pattinson and Barnett are with their relationship, but reports say that FKA Twigs moved from New York to Los Angeles recently and is now staying at Pattinson's home.
