Miley Cyrus is "so sick" of rumours that she and fiancé Liam Hemsworth have hit a rough patch.
The 20-year-old singer-and-actress and the 23-year-old Australian actor got engaged in June of last year after meeting on the set of romantic movie The Last Song in 2009.
Speculation has been rife in recent weeks that the couple's wedding is off.
Star magazine claimed that Hemsworth passionately locked lips with Mad Men actress January Jones at an Oscars after-party in February.
Us Weekly reported the pair were both extremely vexed with each other for spending more time on their professional lives than their relationship.
Cyrus is adamant that all of these assertions are unfounded.
"I am so sick of LA. And sick of the lies that come with it. I didn't call off my wedding. Taking a break from social media," she wrote on Twitter.
Cyrus has recently spoken about how much she enjoys singing her beau's praises in public.
Featured as the cover girl in the March edition of Cosmopolitan magazine, the star gushed about Hemsworth in the accompanying interview.
"I'm the only fiancée that pimps her fiancé out," Cyrus laughed to ET Online last month.
"[I talk] about how hot he is. All these women are reading about sex in Cosmo, and then it's like Liam naked in the pool. So he loves it, I'm sure."
The couple's wedding details have not yet been revealed.
