Singer Alicia Keys is believed to have entered into a secret engagement to boyfriend Swizz Beatz.

A spokesman for Keys denied the report but a friend told Us Magazine: 'They are currently in Hawaii celebrating the engagement and her birthday.

She feels blessed.' The friend added: 'She is thrilled.

She is with the man who has inspired so much of her music and her new album.' Keys is also reportedly eyeing up a $14.5million New York penthouse belonging to Lenny Kravitz, which has been on the market for eight years.

The penthouse is the former home of Nicole Kidman and Denzel Washington.

Kidman had a very brief affair with Kravitz after her divorce from Tom Cruise.

As well as celebrating her engagement, Keys is on course to secure her highest position on the UK album charts with her new album.The Element Of Freedom peaked at number seven after its December release.But it has seen a 48per cent weekly increase in sales following last Friday's performance on Jonathan Ross's show.It's the most unlikely truce in history -- Alicia Keys and Swizz Beatz' ex-wife Mashonda ...the same woman who once publicly accused Alicia of breaking apart her marriage. Barts -- showing Swizz, Alicia, and Mashonda all vacationing together with their children (Swizz fathered kids with both women).It's wild -- nearly 5 years ago, Mashonda wrote a nasty open letter to Alicia in the wake of her divorce from Swizz, blaming Alicia for taking part in the affair that destroyed her marriage and family.
