The couple, only five months away from their wedding, have officially called it quits.
Gross, 28, known for his role on Tyler Perry's sitcom "House of Payne," confirmed the news for his nearly 40,000 followers on Wednesday night.
"Yes it is true," tweeted Gross, who stars in new movie, "Our Family Wedding" with America Ferrera.
Marcille, 25, a previous winner of the popular Tyra Banks show "America's Next Top Model, hasn't tweeted anything to hint at the break-up.
But she did tweet the titles to two very popular ballads, "I will always love u," and "Pretty wings."
The pair did release a joint statement to Essence.com, which said, "Lance Gross and Eva Marcille have mutually decided to end their relationship. The split is completely amicable and both parties remain friends."
The split comes two weeks after Gross was on the Wendy Williams Show taking about his wedding plans.
"We are having a big wedding," he told the talk show host on March 10.
They were set to wed on July 17.
