Patrick Dempsey and his estranged wife, Jillian Fink, are calling off their divorce, People is reporting. "For the past year, Patrick and Jillian have been working on getting to where they are right now," a source told the magazine. "They are not dating anyone else, and only each other." Jillian filed for divorce in January 2015 after 15 years of marriage, citing irreconcilable differences, but recently the pair have been stepping out together again. The two even celebrated Patrick's 50th birthday together earlier this month alongside their three kids, Tallula, Darby, and Sullivan. The makeup artist also posted a sweet photo of them on Instagram, writing, "Happy 5 '0'!!! @patrickdempsey 😉xxx" See their cosy snap below, then check out Patrick's hottest McDreamy moments.
