Is Royalty about to become a big sister? The internet really seems to believe Chris Brown is expecting baby #2.

Brown’s rumored girlfriend Ammika Harris is celebrating her 26th birthday today. But yesterday, she posted an Instagram pic to honor her special day. And the “beautiful gift” she mentioned in the caption definitely added to the speculation that she’s carrying Brown’s baby.

“GETTING OLDER AND WISER EVERY YEAR. IM SO BLESSED WITH THE MOST BEAUTIFUL GIFT I COULD EVER ASKED FOR. HELLO 26!!” she wrote.

The Instagram model is wearing a white lace dress and eagle-eyed fans say they spot a baby bump. A boomerang clip she shared also shows a slight bump as she holds a huge bouquet of flowers.

Brown sparked the pregnancy rumors himself earlier this month.

“BM BAD,” he commented on one of Harris’ Instagram pictures. Though he didn’t explain what “BM” stood for, fans obviously took it to mean “baby mama.”

The couple has been dating on and off for nearly a year and has kept their relationship mostly private. We shouldn’t expect any official announcements anytime soon, but time will most definitely put an end to the rumors and speculation.

Brown has 4-year-old daughter, Royalty, with model Nia Guzman. Harris doesn’t haven’t any children (yet).
