Empire Costars Grace Gealey and Trai Byers Are Engaged!

Just four months after Us Weekly revealed that Empire costars Grace Gealey and Trai Byers were dating, the couple is engaged! Trai, who plays Grace's stepson on the hit show, popped the question on Sunday night during her birthday celebrations in Chicago. "She was totally surprised and elated," a source tells Us. "She can't stop looking at the ring. They celebrated all night."

After their special moment, the couple continued the festivities with more of their costars and posted cute photos on Instagram documenting their night. Trai shared a sweet collage of photos, captioned, "Had so much fun celebrating @gracegealey's life!! Happy Birthday to an exquisite human being! Thank you @kinmontchicago for hosting us. Amazing spot, wonderful food, UNFORGETTABLE night." Grace, who wore an adorable pink dress to ring in her 31st birthday, called it an "incredibly unforgettable day." Congrats to the happy couple!
