Now that news has surfaced that Mariah Carey and her ex-husband, Sony Music chief Tommy Mottola, are back on speaking terms, more about their current relationship is coming to light, reports PEOPLE. Once reportedly at odds, the two are definitely keeping in touch, mostly over business-related items, says a spokesperson at Sony. “There’s been certainly more communication, because her greatest hits record is coming out globally (on Dec. 18), and Tommy has been on a number of (conference) phone calls with her with other executives,” says the company rep. “Tommy has always been supportive of Mariah. He considers himself one of her greatest fans and in that regard nothing has changed.” Carey, 32, who suffered a physical and emotional breakdown last summer, has reportedly been back on the road to recovery and has been seen in public of late, including on the televised all-star “Tribute to Heroes” shortly after the Sept. 11 tragedy. “He is concerned about her,” the spokesperson assured PEOPLE. “He has always been supportive of her, and when she became ill, he made a statement that he was saddened by her illness. He has continued to wish her the very best.” Cindi Berger, the publicist for Carey, also confirmed that Carey and Mottola are again talking, “because they are putting out a greatest hits album.” Berger could not say whether or not Mottola reached out to his ex-spouse after her breakdown.
