Tina Knowles Reacts to Beyoncé's Pregnancy Announcement

Beyoncé just broke the internet when she announced she is pregnant with twins, and while the world freaks out over the news, no one could be happier than her mother, Tina Knowles (a.k.a Tina Lawson).

"WOW I don't have to keep the secret anymore 😀 I am soooo happy God is so good twin blessings," she wrote on Instagram when she reposted her daughter's photo.

Lawson, 63, is already the grandmother of Bey and Jay Z's daughter Blue Ivy Carter and Solange's son Daniel Julez Smith, Jr. By the end of the year, she'll have two new additions to the family.
