AceShowbiz - Both Oppenheim brothers are apparently single. A day after Jason Oppenheim and Chrishell Stause announced their split, Jason's brother Brett Oppenheim revealed that he broke up with his girlfriend Tina Louise.

During an Instagram Q&A on Tuesday, December 21, Brett revealed he was "single." Tina also confirmed the split, writing on her Instagram Story, "Brett is my ex, but we remain very good friends."

Brett further addressed their breakup on his social media page. Gushing over his ex, The Oppenheim Group co-owner said on Wednesday alongside a gallery of photos of the former couple, "I am grateful for you Tina. For your love, your laugh, your smile, and for our enduring friendship."

The real estate mogul went on to say, "Tina is the most genuine… loving…beautiful woman I could have ever dreamed of…with the most breathtaking smile. I will always love her and be her friend." Catching wind of the post, Tina wrote in a comment, "Awwww you lil s**t! Love you always x."

The post arrived just hours after Jason announced that he and "Selling Sunset" star Chrishell were no longer together. "While Chrishell and I are no longer together, we remain best friends and we will always love and support one another," Jason wrote in a post, before hinting at the reason they went their separate ways. "While we have different wants regarding a family, we continue to have the utmost respect for one another."

Chrishell, meanwhile, addressed the breakup in her own post in the later day. "Jason was and is my best friend, and other than our ideas for family ultimately not being aligned, the amount of respect and love we have for each other will not change going forward," the "Dancing with the Stars" alum wrote. "I very much hope to one day have a family and decisions I make at this point are with that goal in mind. Thank you for the kindness and support to those that understand."
