Gabrielle Union has thanked fans for their support after husband Dwayne Wade said she was sacked from her judging role on America's Got Talent.

Simon Cowell's hit show has been marred by controversy over claims of a "toxic" work environment.
It was announced Union, 47, and fellow judge Julianne Hough, 31, would both be leaving the series after joining earlier this year.

US outlet Variety reported Union's contract was not renewed after she expressed concerns over racially sensitive segments in the programme.

Union, an actress and singer known for film roles including Bring It On and Bad Boys II, has now responded to the controversy.

She tweeted: "So many tears, so much gratitude. THANK YOU! Just when you feel lost, adrift, alone... you got me up off the ground. Humbled and thankful, forever." 

Union's message on Twitter came several hours after her husband, who she married in 2014, publicly defended her in a series of tweets on his own account.

Former professional basketball player Wade, said his wife was "fired," writing on Twitter he is "waiting on a good answer" as to why.

He added: "But if anyone knows @itsgabrielleu or have heard of her you know she's an advocate for our community and culture.

"As proud as i were of her being selected as a judge on #AGT— I am even more proud of her standing up for what she stands for and that’s US."

Show creator Simon Cowell, 60, is currently a judge on America's Got Talent, alongside comedian Howie Mandel. Both are expected to return for the next season, as is host Terry Crews.

Replacements for Union and Hough, who filled spots vacated by Mel B and Heidi Klum, have not been announced.
