Tamar Braxton is knocked up ... and pulling a Beyonce Knowles!
The "Braxton Family Values" star announced her pregnancy Wednesday morning on "Good Morning America."
"I have a 'Love on Top,' I'm pregnant," 35-year-old Tamar told Lara Spencer ... referencing Beyonce's performance of the aforementioned song on the 2011 MTV Video Music Awards, where she revealed her baby bump for the first time.
Tamar's sisters, including Toni Braxton, all looked thrilled for the mom-to-be ... who married baby daddy Vincent Herbert in 2008.
"I feel great and greedy at the same time," Braxton added. "This is the most I've eaten, ever."
