Happy Birthday, Beyonce!

Superstar and new mom Beyonce turns 31 today, and her friends have been sending their good wishes!

One of the first to help Beyonce celebrate was best friend Gwyneth Paltrow, who wrote on behalf of her family: “For dear sweet BB on the occasion of her 31st birthday…We love you so very much. Love, Gwyneth, Chris, Apple and Moses.”

Teen idol Justin Bieber tweeted, “oooohh yeah. HAPPY BIRTHDAY BEYONCE!” The birthday girl’s former Destiny’s Child member Michelle Williams sent a note saying, “Beyonce, Happy Birthday to youuuu! I love you so very much. I am so thankful you’re in my life! Love Always, Michelle Williams. P.S. Me & You will never part!”

One of the sweetest and most heartfelt greetings came from Beyonce’s mother-in-law, Jay-Z’s mom “Mama Carter.” She wrote: “God blessed me with one of the greatest gifts in my life on Sept 4, 1981. You came into my life a sweet Southern girl (LOL). You’ve blossomed into an amazing woman. I admire how you remain grounded and humble and haven’t let success change the person that you are.”

It’s been quite a year for the beloved diva, as she and hubby Jay-Z welcomed daughter Blue Ivy. The couple spent the Labor Day weekend enjoying the music and hanging with friends at Philadelphia’s Made in America festival.

Many happy returns, Beyonce, and may all your birthdays be special!
