ET exclusively reported that Sam is the one who filed for divorce.
"After 6 years of love and commitment to each other my wife and I have decided to end our journey together," the 29-year-old wrote Thursday afternoon on his Instagram Story. "We will hold onto the love and respect we have for each other and I wish her the best always. S**t happens. Asking for privacy seems ridiculous so I will just ask for everyone including media to be kind and thoughtful."
A rep for Asghari is also setting the record straight on a number of stories floating around since the breakup became public.
"There are many claims that Sam is challenging the prenup and threatening to exploit his ex-wife with videos. However, all these claims are false, as no negative intention has ever been directed towards her and never will be," Asghari's rep tells ET. "Sam has always and will always support her."
A source tells ET that Britney Spears' prenup with Sam Asghari is "rock solid."
Sam's statement on IG comes one day after ET exclusively reported that it was he who decided to officially pull the plug on the marriage by filing for divorce after one year of marriage. The divorce filing came just hours after ET first learned that he and Britney, 41, decided to split up.
As for the reason behind the split, a source told ET that a cheating allegation may have led to the breakup. A source told ET, "Sam believes that Britney cheated on him" and "he believes he caught her in a lie and it caused him to be done with the relationship."
But another source told ET that Britney is "adamant she didn't cheat." The same source added that "the two haven't gotten along for a while and it finally came to an end after a major blowup."
Sam's public statement came just one day after the pop star took to Instagram and declared she was planning to buy a horse.
"Buying a horse soon 🐴 !!! So many options it’s kinda hard !!! A horse called Sophie and another called Roar 🐎 ??? I can’t make up my mind 🙈 !!!" Britney shared with her 42 million followers on Instagram. "Should I join the camaraderie and put a pink cowboy hat on 😜 ??? Either way I think I found my sweet spot with Roar 😘 !!!"
The message was posted along with a photo of the singer riding a horse on the beach wearing a bikini top, shorts, sandals and a hat. The pic is from when she and Sam went horseback riding together, which they both posted about in July. She did not address the divorce or her estranged husband, and she turned off the comments in the post.
