Singer Jay-Z is fascinated by the giants of our oceans and wants to learn more and help them... and he wants his daughter, Blue Ivy, to learn about them too.

So... Jay-Z, along with Blue Ivy and her mother, American pop icon Beyonce Knowles, went on a whale-watching trip to Hawaii! To see the photographs, click here.

"Jay-Z is really interested in creatures that live underwater. He started reading about blue whales a while ago and has become hooked on finding out more about them. He's been looking into funding research into the rare species as so much about them is still unknown," a source told The Sun.

Blue was strapped into a baby carrier and wrapped in a grey blanket, and she appeared to be wearing a simple white onesie. The superstar singer dressed for the warm weather in an orange cardigan and denim cut-off shorts which showed off her enviable pins. She tied her honey coloured locks into a French plait and had a multi-coloured bag slung over one shoulder. Jay-Z looked very casual in his white Breton top, blue jeans and white tennis shoes. The pair each wore sunglasses for their day of exploring the waters in the sunshine, and when they returned from the boat trip, Beyoncé wore a different cardigan, a report in the Daily Mail read.

Meanwhile, Beyonce and Jay-Z have reportedly renewed their vows, on the occasion of their foruth wedding anniversary. According to, the couple exchanged rings in front of celebrities like Oprah Winfrey, Will Smith and Jade Smith.

Furthermore, Beyonce is going public. The singer has re-launched her Web site, detailing more information about her private life.

"This is my life, today, over the years - through my eyes. My family, my travels, my love. This is where I share with you. This will continue to grow as I do," the singer wrote on her revamped Web site.
