However last night in London the star made a very public coming out with her boyfriend, just weeks after his divorce was finalised.
Alicia, 29, and Swizz, 31, were seen heading back to her hotel in London after her sell out show at London’s O2 Arena.
Their arrival in London follows the couple’s first red carpet appearance together back in March at the Gotham Magazine annual gala in New York.
Dressed in a very short black minidress with black cage bootees the 29-year-old looked radiant as she clutched Swizz’s hand.
Swizz has been separated from former wife Mashonda since April 2008, and now that the divorce has been finalised it seems the couple are ready to embrace the spotlight.
The 31-year-old producer has been involved in a messy divorce from singer wife Mashonda who at one point released a letter on Twitter blaming the Grammy award-winning singer for the failure of the couple’s marriage.
Swizz – real name Kasseem Dean – who has created hits for Jay Z and Whitney Houston has denied the claim while Alicia has maintained a dignified silence.
The pair are rumoured to have become secretly engaged to Alicia in Hawaii earlier this year. And if reports are to be believed, they may have something else to celebrate.
Alicia’s appearance onstage at the O2 last night increased speculation that the singer may be pregnant.
She wore a loose-fitting top for the first part of her show. But photographers were only allowed to take photos for the first two songs. And after they left she changed into a grey strapless jumpsuit, which did little to dispel the rumours.
A source told Mail Online: ‘Alicia looked stunning on stage, but the jumpsuit looked suspiciously full in the front section.’
However, seen last night looking stunning in a black belted minidress, there was certainly little room to hide anything in the revealing outfit.
Swizz has two sons, Kasseem Jr from his marriage to Mashonda and Prince Nasir from a previous relationship.
Meanwhile the Empire State Of Mind singer who is celebrating the success of her fourth studio album The Element of Freedom has revealed she hopes to collaborate with friends U2 in the future.
