Beyonce and Jay-Z have been known for being notoriously private over the years, but with the birth of their daughter, Blue Ivy Carter, and the celebration of their fourth wedding anniversary, the superstar couple is opening up more.

Yesterday Beyonce and Jay-Z celebrated their fourth wedding anniversary and as their fans know, four is a very important number in their lives. They were both born on the fourth of the month, Beyonce's mother and sister have birthdays on the fourth, they were married on 4/4/2008 and their daughter's name is said to represent four as Ivy is the roman numeral for four and blue is said to be for blueprint, which if Jay-Z recorded another blueprint album it would be the Blueprint 4. Jay-Z was spotted out yesterday at celebrity favorite jeweler, Jacob & Co., with Jacob the jeweler, perhaps picking up a gift for wife, Beyonce.

Today Beyonce gave fans a look into her personal life with the launching of her new Tumblr page. The page features over 150 personal pictures of Beyonce, Jay-Z and her family. The Love on Top singer also relaunched her website including the pictures from the Tumblr page and new sections for her Beyhive to be able to keep up with The Queen Bey.

Beyonce and Jay-Z's first foray on to Tumblr was with the release of Blue Ivy's pictures. The new parents posted pictures of their newborn daughter, when she was four weeks old, on the site along with the message, We welcome you to share in our joy. Thank you for respecting our privacy during this Beautiful time in our lives. The Carter family.

Beyonce also sent out her first tweet accompanying the release of her Tumblr page and new website, Hey World, It's B! I'm so excited to invite you to my new - we've been working hard, and it's finally ready for you XO. She has been on Twitter for over a year, but has never sent out a tweet until today. The website revamp was done by Matthew Siskin, who tweeted earlier, I'm not sleeping till we're done.

Beyonce is revving up for her first post-baby concert at the new casino and resort, Revel, in Atlantic City. She will be the first performer to headline at the $2.4 billion resort and will perform three dates over Memorial Day weekend. Tickets go on sale tomorrow through Ticketmaster, April 6, at 10:00 a.m.
