*Every celeb and their mama congratulated Beyonce on the birth of her daughter Blue Ivy Carter, including Rihanna, Gwyneth Paltrow and Russell Simmons.

Not on the list? Beyonce’s former Destiny’s Child member Michelle Williams. Folks on the Interwebs are now wondering what’s up.

“In response to one follower who suggested she needed to send a message of congratulations, Williams tweeted: “Let’s get ONE thing straight….I do NOT have to say congrats to someone when they’re NOT on twitter. …ESPECIALLY when I talk or email them all the time….or when I’ll be physically present as well.”

“My friendship with people aren’t always for twitter display,” Williams continued. “Respect that and get a LIFE!!! Enjoy this FINE day!!! God bless!!!!”

In a follow-up Tweet, Williams said, “This is a beautiful, precious, private time between two people and excitement is to be expected but NOT disrespect!”

And to end the mini-rant, Williams used this hash tag: “#churchdismissed.”
