Kristen Stewart is reportedly banned from her ex-boyfriend's wedding. The reason? Robert Pattinson's fiancée FKA Twigs allegedly ordered him not to invite KStew to their upcoming nuptials. While RPattz and Twigs have been rumored to have broken up last month, their wedding is still on.

Why did FKA Twigs ban Kristen Stewart from her wedding to Robert Pattinson? Is she jealous? According to Fashion & Style, the 27-year-old "Two Weeks" singer was driving her 29-year-old fiancé away by forbidding him to invite KStew.

The rumors, however, seemed to be false. As per Gossip Cop, a source close to Pattinson and Twigs slammed the speculations that Kristen Stewart has been banned from the wedding, calling the rumors "stupid" and "wrong" in every way.

Meanwhile, Robert Pattinson and FKA Twigs' rumored breakup came just days after Twigs sent fans into a frenzy when she posted a photo of herself wearing what appeared like a wedding dress on Instagram. But the couple continue to remain mum about the news of their engagement as well as their upcoming wedding details.

Kristen Stewart, who is known to have a serious face, was allegedly disliked by ex-beau Robert Pattinson's family. And they prefer RPattz's new fiancée FKA Twigs more than the "Clouds of Sils Maria" actress, Design & Trend revealed.

"They've never seen him more in love, not even with Kristen," an insider told Hollywood Life last year. "[Rob's sister] Lizzy has a strong connection with FKA Twigs because they're both singers. What's impressive to Rob's sisters is that FKA twigs is interested in them and getting to know them."

"[FKA is] very engaging with them and Rob's parents, whereas Kristen was more reserved and closed off," the source added. "They feel like FKA twigs has pure intentions and that her affection for Rob comes from the heart. They don't have any fears of her using Rob because of his fame or anything like that."

While Kristen Stewart was accused of being unhappy for having a serious face expression, the former "Twilight" star defended herself in Elle UK's September 2015 issue.

"The whole smiling thing is weird because I actually smile a lot," the 25-year-old actress said, as quoted by Us Weekly. "I literally want to be like, 'Dude, you would think I was cool if you got to know me.'"

Unfortunately, fans won't be able to know her through social media platforms since Kristen Stewart doesn't have an Instagram, a Twitter or a Facebook account.

"The idea of addressing such a massive group... If I don't know who I'm talking to, it doesn't make any f-king sense to me," she admiited.
