Alicia Keys and Swizz Beatz

Singer Alicia Keys may be taking her relationship with boyfriend, producer Swizz Beatz, to the next level and getting married. Rumor has it that the 29-year-old is "secretly" engaged to Swizzy, despite her rep's claims to the contrary. The story arose when Keys was photographed sporting a rock on her ring finger while on vacation in Hawaii with Swizz.

The two have been making headlines since getting together in 2008. Most notably, Swizz's ex-wife Mashonda has been very vocal about in her disapproval of their relationship, claiming that Keys caused the break-up of her marriage. "My concern with AK is no longer the fact that she assisted in destroying a family but that she has the audacity to make these selfish comments about love and wanting to be with someone, even after knowing their situation," she wrote in an open letter to Keys via her Twitter page. "You have no idea how much pain I was caused because of this affair, It's baffling to me that you don't understand what I might have gone through with this situation," Mashonda added.

Both Swizz and Keys rarely speak about their relationship but have been traveling and spending lots of time together in recent months. Despite playing coy about his love for her, Swizz briefly spoke about his love for Keys, telling the New York Daily News that they're taking things slow. "We're nowhere near ready for a baby or a ring," he told the newspaper in an interview last year. Swizz may have had a change of tune.

No word yet on how Mashonda is taking the news of the possible engagement.
