Rumor Mill: Enrique & Anna Engaged?

It's that time of the year again!

Rumors are once again flying that Anna Kournikova and her Latin lover boyfriend, singer Enrique Iglesias, are engaged after the former tennis star was spotted sporting a large rock on her hand.

Perhaps trying to throw off the scent, the 26-year-old bombshell flashed the reported $6 million diamond stunner on her right ring finger while out in London on Tuesday. Meanwhile, her left ring finger remained occupied with a gold band.

The couple has long fought off rumors of engagements and marriage over the course of their relationship, specifically every two years — in 2003 and 2005.

Anna and Enrique, 32, began dating after she appeared in his "Escape" video in 2002.

Calls to Enrique's rep for comment have not yet been returned.
