As Miley Cyrus prepares for the release of her documentary "Miley: The Movement," the singer is once again dealing with another pregnancy rumor. Recently, there was a rumor that she and now ex-fiancé Liam Hemsworth were trying to work things out because she was carrying his baby.

The 20-year-old singer hasn't commented on the report but did laugh off a new report that she is expecting her first child with rapper Juicy J. According to several reports, Cyrus reportedly told the crowd while performing at the BET Hip Hop Awards that she was pregnant with the rapper's child.

She joked about the news on Twitter writing: "waking up to the news that I'm now pregnant with @therealjuicyj baby."

She then tweeted: "Me: did you know I'm pregnant with @therealjuicyj baby this morning @CheyneThomas: what are you gonna name it? Me: Juicy J Jr DUH.'

It doesn't seem like the singer is taking the latest rumor seriously but instead focusing on the release of her MTV documentary in which she attempts to explain her now infamous VMA performance with Robin Thicke.

In a snippet she explained that she wanted to do something shocking to help her shed her "Hannah Montana" image in hopes of finally becoming the "bad bitch" she really is.

According to US Weekly, Cyrus seemed very well aware of the backlash she was getting over the performance - in fact it was exactly what she had planned. The revelation comes from a snippet of her documentary shot three months before the performance and shortly after.

"I just needed to let go of the past in a way so I felt like I could be the bad bitch I am," she said in the video.

She went on to further explain the VMA show and her controversial leap into adulthood - with giant foam fingers, dancing life-size teddy bears and barely-there clothing - took very careful planning.

"You can watch that performance and think that's a hot mess,' she said. "But it's a strategic hot mess... if I wanted a raunchy sex show, I wouldn't have dressed as a damned bear."

"How many times have you seen this play out in pop?" she continues. "Madonna's done it. Britney [Spears has] done it. I'm onto the next one. Yes, I am very comfortable with my sexuality."

According to US Weekly, the "We Can't Stop" singer is even seen in the video telling Spears that she thinks people take the VMAs too seriously and she wanted to have some fun with her performance.

The hour-long documentary, which airs Oct. 2, also follows the singer as she does appearances to promote her single "We Can't Stop," in rehearsals and at her Los Angeles home with her dogs.

The one thing viewers won't see in the documentary is her ex-fiancé Liam Hemsworth. Reportedly an executive vice-president at MTV and the executive producer of Cyrus' documentary said the "Hunger Games" actor wasn't featured because they decided to focus on Cyrus' music career and professional side instead.

Cyrus and Hemsworth ended their engagement on September 16 after months of speculation that they were having problems.
