India, July 18 -- Hollywood actor Pete Davidson, 31, is going to be a father! He is expecting his first child with girlfriend, actor-model Elsie Hewitt, 29. The couple took to Instagram to make the announcement. Sharing beautiful pictures of them, a pic of the sonogram and a video from their hospital visit, Elsie captioned the post, "welp now everyone knows we had sex (sic)". The news comes months after Pete and Elsie first grabbed attention during a getaway to Palm Beach, Florida (USA). They were photographed sharing a kiss while enjoying a day at the beach. Shortly after the photos surfaced, a source told People that the couple was officially dating. In May, an insider said that they had already taken the next step in their relationship by moving in together. "Pete and Elsie have been living together in New York for the past few months. They are splitting their time between Pete's house in upstate New York and a brownstone they recently started renting in Brooklyn," the source said, adding that the couple was "so happy together and doing great".HTC...
