Jennifer Lopez is "bored" of being wrongly accused of planning to tie the knot again.

The stunning songstress has been dating her backing dancer Casper Smart for several months, following her split from her third husband Marc Anthony.

Numerous reports have claimed Jennifer's romance with the 24-year-old is heating up considerably, with speculation rife that the 42-year-old beauty is ready to walk down the aisle for a fourth time.

Jennifer is fed up of the constant speculation surrounding the state of her relationship.

"I keep seeing something about getting married. Surprise, surprise "they" are wrong...AGAIN. #boredtweet (sic)," she wrote on her Twitter page.

The American Idol judge was reported to have tied the knot with Casper on a Mexican vacation by one publication, but her spokesperson has rebuffed the rumour.

"[The tabloid] story is completely false," Lopez's spokesperson told Us Weekly.

A posting on fashion designer Roberto Cavalli's Twitter page last week claiming he was working on a wedding gown for Jennifer further fuelled speculation.

The comments appeared on the designer's personal profile at the beginning of the week, but were deleted soon afterwards.

"Today , Jenifer Lopez. Call me...... She ask me. To create a special dress. For her next weding. !" he appeared to tweet. "Wich color ... Do you advise me. (sic)?"

Roberto's representatives vehemently denied the designer had written the posts, claiming his account has been hacked into.

The beauty's representatives also denied reports of a marriage at the time.

Jennifer filed for divorce from husband Marc Anthony in July last year after seven years of marriage.
