As the day for Miley Cyrus and Liam Hemsworth's marriage ceremony this summer nears, the "Wrecking Ball" singer is having "second thoughts," Radar Online reported. The news comes amid rumors that Cyrus is pregnant with Hemsworth's child.

“The wedding is going as planned and will be happening soon,” the source close to Cyrus told Radar Online. “But Miley is getting really, really antsy.” The source said that the two "are not seeing eye-to-eye on things right now and she is starting to realize that she could be living a lie for the rest of her life!”

Cyrus and Hemsworth, who have not publicly addressed rumors about their wedding, got engaged in 2012 but ended their relationship in 2013. The two rekindled their romance in December 2015 after the singer spent Christmas with the 26-year-old “Hunger Games” actor and his family in Australia. Since then Cyrus has been flaunting the diamond ring Hemsworth gave her during their 2012 engagement.

Since the two got back with each other, several rumors about their engagement and wedding surfaced. Some reports also claimed recently that the couple had once again broken up. Cheating and pregnancy rumors also made the rounds.

However, Cyrus and Hemsworth's time together in Malibu during the Fourth of July weekend quashed rumors about their split. But pregnancy rumors resurfaced after the 23-year-old was seen holding a knapsack in front of her while walking. OK! magazine reported that Cyrus was “caught covering her mid-section with a backpack,” speculating she was pregnant.

Meanwhile, the Radar Online report on Thursday reported that Cyrus is “not ready to settle down and have kids."

“Liam seems to want Miley to be this squeaky clean housewife and she just is not,” the source continued. “There is no doubt that she is madly in love with him. But this marriage has disaster written all over it!”
