Kathy Hilton, Paris Hilton's mother, reportedly posted a tweet Sunday, saying that Jennifer Aniston is pregnant and also mentioned that she will have a baby girl. Following the post, Aniston's publicist, Stephen Huvane, told Hollywood Life on Monday that "Jennifer is not pregnant nor does she know Kathy Hilton."

Kathy Hilton reportedly removed the post from Twitter later.

Kathy Hilton told her more than 100,000 Twitter followers that Aniston looked stunning during the Oscars ceremony Sunday and claimed that she was pregnant. However, Aniston's plunge-neck Versace gown that stuck to her body gracefully apparently told a different story.

Kathy Hilton had reportedly written in the now-deleted tweet: "Jennifer Aniston looks so beautiful tonight I am telling you she is having a baby girl 100 percent!!!!!!!!!!!" Her tweet was also decorated with numerous smiley faces, flowers and four-leaf clovers. It caused some confusion among Twitter users and someone also went on and asked if she meant Natalie Portman, who is expecting a second baby with husband Benjamin Millepied. Some users thought it could be true because it came from Kathy Hilton, however, others said she was only making a guess, according to the Mirror.

Aniston, who married Justin Theroux in August 2015, has often faced several pregnancy rumors. Last year when she was photographed having a larger belly than usual, she was forced to respond to the rumors and said she had a "big lunch."

"For the record, I am not pregnant. What I am is fed up. I’m fed up with the sport-like scrutiny and body shaming that occurs daily under the guise of 'journalism,' the 'First Amendment' and 'celebrity news.' We are complete with or without a mate, with or without a child. We get to decide for ourselves what is beautiful when it comes to our bodies. That decision is ours and ours alone. Let’s make that decision for ourselves and for the young women in this world who look to us as examples," Aniston wrote in a letter, published on the Huffington Post.

"I resent being made to feel 'less than' because my body is changing and/or I had a burger for lunch and was photographed from a weird angle and therefore deemed one of two things: 'pregnant' or 'fat,'" she added.
