She may be head over heels for beau Casper Smart, but Jennifer Lopez swears her bling doesn't mean a thing.

Recently, the pop star sparked rumors she and her love of eight months were taking a big step forward in their relationship when she was photographed sporting a diamond sparkler on her ring finger.

"Rumors!!! Don't be fooled by the rocks that I got," Lopez, 42, wrote on her website Friday, quoting her 2002 hit, "Jenny From the Block". "No engagement!"

The American Idol host -- who split from husband Marc Anthony last July -- first stepped out with backup dancer Smart last fall. (The 25-year-old even spent Thanksgiving with Lopez and her twins with Anthony, Max and Emme, 4.)

In April, Lopez opened up to Vogue about her attraction to her new man.

"He's adorable. But you already see that," she gushed to the mag. "He really is [sweet]. He's a good egg. I don't want to talk about it too much. It's my private thing."

As for their 18-year age difference? Said Lopez, "I don't feel older and I don't feel like I look it, either, so I'm just acting the same way I have always acted."
