Lori Loughlin is dipping her toe back into the dating pool five months after separating from her estranged husband, Mossimo Giannulli. "Lori has been putting herself back out there after her split from Mossimo and is dating again," a source exclusively tells Us Weekly, noting that the actress, 61, is "just having fun and keeping things light and casual." The insider adds, "It is nothing serious," but Loughlin "feels like she got her spark back" after her split from Giannulli, 62, in October 2025. "[She] is in such a good headspace lately," the source says.
