Paris Jackson, the daughter of the now-deceased Michael Jackson, is shutting down rumors she secretly married her boyfriend Chester Castellaw. The 17-year-old sparked marriage rumors this week, but she quickly dismissed the speculation in a new Instagram post Saturday.

Sharing a photograph of herself on the social networking site, Jackson wrote, "Thank you guys for reaching 200K  followers! #loveyousomuch." She added, "P.S. I'm not married and no, I'm not pregnant lmao."

Earlier Saturday, TMZ reported there was a chance Jackson had secretly wed the 18-year-old soccer player when she added his last name to hers on Instagram.

Radar Online reported that Jackson was eager to marry Castellaw and was hoping to walk down the aisle shortly after her 18th birthday in April. The site also claimed her family wanted her to slow down and sign a $2 billion prenuptial agreement before she married the athlete.

"It's a dilemma," a source told the site. "Family members want Paris to get going on her prenup, but they're walking on eggshells. They don't want to get her angry or, worse, have her cut them off."

Paris Jackson's co-guardian T.J. Jackson previously opened up about her relationship with Castellaw, telling ET Online in August he approved of the romance. "No one's perfect, but he’s a good boy," he said. "He treats her well. She's happy."

Paris Jackson and Castellaw were first linked as a couple in April when they were spotted hiking together in Los Angeles. The pair confirmed they were dating on Facebook a month later. They made their first red-carpet appearance in May at the Deaf West Theatre's production of "Spring Awakening."
