Did Sofia Richie find a new man while boyfriend Scott Disick was in rehab? The 21 year-old beauty is seen hiking in Malibu with her pup and with pals and looks to be getting awfully cozy with a hunky male companion. Disick checked into rehab on April 28 as he still struggles to cope with the loss of his parents, who passed away in 2013 and 2014. Within a week of treatment, Disick left the facility. Sofia's been chilling at a Malibu rental -- previously with Scott -- but is she solo in the house now or maybe with this mystery man??? They seem pretty close!
