London: Pregnant singer Beyonce Knowles turned 30 in style celebrating her birthday with a romantic dinner date with husband Jay-Z.

The 'Single Ladies (Put A Ring On It)' hitmaker, who revealed at last month's MTV Video Music Awards (VMAs) that she and her rapper spouse are expecting their first child
together, made her first public appearance in Venice since the announcement, according to reports.

Onlookers observed that Beyonce looked "radiant and happy" as the pair left their hotel, with a protective Jay-Z holding his wife's hand.

The couple tied the knot in 2008 and wanted to enjoy their first few years of marriage before having children.

"She and Jay wanted to focus on their careers and enjoy the first years of their marriage. Now, with everything so perfect in both those regards, she can't wait to be a mom," a source said.
