Jennifer Lopez and Casper Smart Planning Wedding in Mexico?

Jennifer Lopez is reportedly planning to marry her 24-year-old boyfriend, Casper Smart, in Mexico and friends and family have become increasingly concerned, according to new reports.

"Everyone in Jennifer's inner circle thinks she's lost her mind. Her mom, Guadalupe, flat out told her that marrying Casper will be the biggest mistake of her life!" a source told Star magazine.

"Jennifer called her mom, sister and a few trusted friends from Acapulco … She said that she and Casper decided to get married in Mexico. Her mom … thought they had eloped, but Jen just laughed and said it was only a matter of time," the source added.

Lopez, 42, filed for divorce from singer Marc Anthony in July and although the estranged couple is yet to finalize their divorce. The "On The Floor" singer is preparing to marry Smart, who is a professional dancer.

The mother of two has already finalized a prenuptial agreement, which requires her to pay Smart $1 million each year for 10 years in the event that they get divorced, the magazine claims.

"Jennifer's gut is telling her that Casper is marriage material. And there's no talking her out of something once she sets her mind on it," another source told Star.

Renowned Italian fashion designer Roberto Cavalli recently fueled the wedding rumors after tweeting what some critics say is evidence that Lopez is marrying Smart.

"Today, Jennifer Lopez. Call me. She ask me. To create a special dress. For her next weding! (sic) Wich color ... Do you advise me?" Cavalli tweeted, before insisting that his account was hacked.

Smart was recently forced to defend the 18-year age gap between him and Lopez and took to Twitter to address ongoing criticisms.

"Age, status, n opinions of others are irrelevant. Our hearts are endless and our souls infinite...To be continued," Casper tweeted.

"Our ages are mere reminders of the hours logged on this earth and the precious time remaining...To be continued," he wrote.

"We should all honor our time here by indulging our passion and dreams. So, close your ears and open your hearts; Love and be happy!" he later added.
