Jennifer Lopez turned heads at the 2015 Met Gala, where she strutted the red carpet in a dazzling, sheer dragon dress. But her sexy and revealing attire is not the only reason people were talking. The Puerto Rican diva was also spotted with a big rock on her ring finger, which left many wondering if there are wedding bells ahead and if Casper Smart will be her new hubby. 

Word on the street is that JLo, 45 and her on-and-off 28-year-old boyfriend, are planing "a secret $3 million wedding" and that "arrangements have been in the works since December," reports Life & Style. The magazine also notes that Lopez accepted the marriage proposal once Smart agreed to sign a pre-nup. She's also determined to make this marriage her last one with the intention to "live happily ever after." “She’s positive Casper is the one,” an insider tells Life & Style. “And she’s willing to pay a fortune to make her wedding day perfect.”

Neither Lopez nor Smart confirmed the chisme, but if it's true, we wish the couple nothing but the best! Also, check out the rock she was rocking at the 2015 Met Gala. What are your thoughts?
