Robert Pattinson and FKA Twigs may be more in love than ever, but FKA is said to be displeased with the "Twilight" star's body. FKA, who is a trained dancer and has a penchant for fitness, is said to outdo her boyfriend in the bedroom, making her wish Robert can diet better and exercise more.

According to a report by OK magazine, FKA is trying to force Robert to be more fit and healthy. She wants him to follow a strict diet regimen and exercise schedule. Not because Robert looks unfit or fat, but because she thinks Robert can have more stamina in the bedroom with a fitter psyche. The diet, for FKA, should include lessening Robert's drinking. "FKA's so fit it's not funny and she outperforms him in the bedroom all the time," the source shared to OK exclusively. "He's very unfit, smokes and drinks way too much, but she's convinced him he'll be much happier if he's more healthy."

The report details that FKA, whose real name is Tahliah Debrett Barnett, is introducing him to a list of good and healthy foods to eat, restricting his booze to low-calorie spirits, and forcing him to pump barbells whenever he has free time. While FKA's intentions to get Robert fit can be lauded, the repot says the actor's friends and family do not like FKA's ways of changing Robert, starting with his edgier hairstyle. The source goes on to say that Robert's new haircut was a real shocker to his friends and family. Moreover, friends and family of the actor think he is having too much of a good time with FKA, partying too much, and then acting like a "space cadet" when with them, the source says.

Moreover, those who have known the Kristen Stewart's ex-boyfriend allegedly said Robert is too impressionable and easily persuaded to do things. They said that because he was a nerd growing up, he's currently making up for the lost time and trying to "be cool." No matter what they say to him however, Robert is said to be not listening as he prance around with his "cool new style," and spending more time with FKA. Hollywood Life just reported that the two are already making marriage plans.
