'Selling Sunset' Newbie Chelsea Lazkani Raves About 'Great Relationship' with Costar Christine Quinn Irma Lomidze | @irmalomidze 'Selling Sunset' Has a Season 5 Premiere Date — and a New Cast Member! Meet Agent Chelsea Lazkani The British-Nigerian luxury realtor joined the cast of Selling Sunset in season 5. However, Lazkani was accomplished in her field prior to becoming part of the Oppenheim Group. After exiting the corporate world in 2017, she obtained her real estate license and joined Los Angeles agency Rodeo Realty (the former employer of Million Dollar Listing Los Angeles star Josh Flagg). After venturing out on her own and taking time to raise her two children with husband Jeff Lazkani, she realized she was ready to return to the real estate game. Christopher Horne "I think having the support of my husband and my family really essentially prepared me to take on this big role and this big opportunity," Chelsea told PEOPLE in May. "But for me personally, I saw this as an opportunity to really open doors in an industry that has lacked diversity and where minorities are underrated." She added: "I feel like with great opportunities comes great responsibility. This was kind of my time to give back and to educate and really mentor and push forward Black women in this luxury sector in real estate. So just knowing that I've got a greater purpose kind of prepared me for this." Irma Lomidze | @irmalomidze Heather El Moussa Recalls Surprising Question Husband Tarek Asked Her the Day They Met: 'I Said No' She "was always very familiar with Oppenheim Group" prior to joining, but she hadn't met any of her other co-stars on Selling Sunset, all of whom, she says, have "really inspired" her. "It kind of helps me see my future trajectory by being around so many successful women," she said. "It helps materialize the fact that I can be selling $20 million, $30 million, $40 million homes, seeing other women in close proximity to me doing it."
