Robert Pattinson Jealous: FKA Twigs Onstage Sex Appeal Upsets 'Needy' Fiance, Wedding Now Off?

Now that English songstress FKA Twigs' music career continues skyrocketing, is 29-year-old "Twilight" heartthrob Robert Pattinson worried that he made the wrong decision by proposing marriage? Well, beloved ex-girlfriend Kristen Stewart ended-up cheating once her fame and fortune grew, so...

Now rumors suggest that Pattinson's concerned history might repeat itself.

Twigs continues touring the world, and her outstanding performances are extremely artistic and unique. Maybe even a bit too sexy?

According to the seedy gossip tabloid Star magazine, R-Patz is now fighting with his 27-year-old fiancee because she's getting way too "sexual" with male backup dancers ongstage. An alleged insider explains:

"Ironically, it's the kind of edgy mystique that attracted Rob to her in the first place... But now he seems to have become jealous and controlling, and he wants her to tone it down."

Apparently Pattinson already has major issues trusting women, since 25-year-old Stewart broke his heart several years ago.

Anyway, the snitch continues:

"FKA thinks Rob is suddenly being very old-fashioned, and to her, just because there's the possibility they'll tie the knot shouldn't mean she has to change who she is."

Now, the "Glass & Patron" crooner's getting annoyed. After a recent concert, a supposed backstage "eyewitness" overheard Twigs ranting on the phone to a friend about her beau's insecurities:

"It sounded and felt to me like she and Rob had recently had it out... She was saying that he was mad she was being too sexy and she wanted him to be more understanding of her art."

Twigs now considers Pattinson very "needy" and "overprotective." Really?

Will such nonstop bickering ultimately ruin their "happy" relationship?

Hopefully not. Another "legit" source for GossipCop.com insists that such seedy rumors are completely untrue. No friction currently exists between the couple, and Pattinson is overly proud of his lover's growing success. Now when will those wedding bells finally go off!
