Shakira and Gerard Pique's cute 'parent to parent' exchange with new dad Mark Zuckerberg

Mark Zuckerberg and his wife Priscilla Chan had barely welcomed their adorable daughter Max when the good wishes from famous friends started pouring in. One such congratulatory message came from singer Shakira and her partner, Gerard Piqué, who penned an open letter on Facebook "from parents to parents."

As well as offering their congratulations on the birth of baby Maxima, Shakira and Gerard also praised the couple for their decision to donate a substantial amount of their Facebook shares to help children all over the world.

"Your commitment to making the world a better place than you found it, and to empowering everyone to help make that a reality through all the tools you've listed here, education for all being one of them, show that success, when shared, has a multiplier effect," Shakira wrote. "It's not about leaving anyone behind. It's about helping pull everyone, and humanity in general, forward."

Mark was quick to reply, saying, "Thanks Shakira and Geri! Your work with the United Nations has been an inspiration and we've enjoyed discussing each of our education projects together over the years. We look forward to you guys meeting Max soon!"

Shakira and Gerard were not the only famous faces to post their best wishes on Mark's Facebook page; Bill Gates's wife, Melinda, Martha Stewart, Maria Shriver and actress Ashley Judd were among those who congratulated the couple.

Mark announced the birth of his daughter Max at the weekend.

Fellow entrepreneur Richard Branson described Mark and Priscilla's letter as "magical," adding, "Commitments like this from the next generation of young entrepreneurs means the world can and will sort out its remaining problems."

Facebook CEO Mark announced the happy news that he and Priscilla had welcomed their first child together on the social networking site on Tuesday. The new father shared a lovely photo of the three of them and attached a moving letter to their newborn baby after thanking everyone for their "love and support" during Priscilla's pregnancy.

It was Mark's revelation that they would be donating 99 per cent of their shares to help children all over the world that elicited an even stronger reaction, with the generous entrepreneur explaining, "We are committed to doing our small part to help create this world for all children. We will give 99 per cent of our Facebook shares -- currently about $45 billion -- during our lives to join many others in improving this world for the next generation."
