Jennifer Lopez, 44 was given a ring from her boyfriend Casper Smart, 26, but denies engagement rumors, according to The Inquisitr.

The vintage diamond ring was a birthday gift from the backup dancer, who also tweeted out to J. Lo, "HAPPY BIRTHDAY to my very very beautiful bear the nicest, sweetest, funniest, sexiest bear there is! Love u."

People magazine talked with Platt Boutique owner Larry Platt, who was able to provide more details about the non-engagement ring.

"[Casper] told me he had bought her jewelry before, but never vintage so he wanted to go in a different direction, something one-of-a-kind."

The storeowner also said Smart knew a lot about what Lopez, recently divorced from Marc Anthony, was looking for in jewelry.

"He has a very good eye and knew what he wanted...He was looking for vintage pieces that had a chic, modern feel to them.  He told me that there are only two pieces of jewelry that Jennifer wears on a daily basis, so he wanted to pick pieces that he felt she would wear all the time and could go with everything."

Platt added that Casper "appreciated the fact that pieces were beautifully made, from a different era, and were completely unique."

It seems as though Lopez likes the "unique" piece, too. 

According to Entertainmentwise, Lopez has been wearing the ring on her ring finger for over a week, but that her reps were quick to deny the engagement rumors. 

The former American Idol judge has been married three times, and has two children.
