According to TMZ, Rose and the couple's 2-year-old son meet Wiz Khalifa at his Calabasas home, where he threw a "big Easter party."
The couple was photographed stepping away from the crowd during the gathering to enjoy time with their son.
The encounter comes at the heels of Rose's declarations that she "prays, dreams and hopes" she and Wiz Khalifa will get back together.
The 31-year-old model filed for divorce in September after a year of marriage. She claims the relationship ended because Wiz Khalifa was unfaithful, but the rapper has vehemently denied any wrongdoing.
