Star couple Beyonce Knowles and Jay Z along with their daughter Blue Ivy jetted to Naples, boarded a $900,000-a-week yacht called the Galactica Star, and took a detour to Capri.

For Beyonce's 34th birthday this month, Jay Z whisked her away to their world. `It's tradition now,` a source told usmagazine.com of their trip to Italy. `Almost every September, they head to Italy and France and charter an überluxe yacht for a week or two.`

After Capri, they also went on to the Amalfi Coast and Sardinia.

`Now that Blue's older, they enjoy showing her the places they've grown to love,` the source said.

They made the experience a family affair and had friends join them including singer Kelly Rowland.

`Blue loves her,` the source said of the former Destiny's Child member. `Blue's been having fun with Kelly so Bey and Jay get a little alone time in`.
