Donald Trump Jr. and Fox News host Kimberly Guilfoyle have made their relationship public on Instagram, as the two shared a series of posts from their romantic fly-fishing trip to Montana over the weekend. The couple visited Montana for the state's Republican Convention in support of Senate candidate Matt Rosendale, where during his speech Trump Jr. confirmed that the two were dating. 

According to a report on Vanity Fair, Trump Jr. addressed to the crowd while thanking Guilfoyle for joining him on his trip. The article quotes him saying, "Just as everyone else thanks their significant others, I got to thank Kimberly for coming out here. We’re going to take her fishing tomorrow, then shooting,” he said to the crowd, also noting that he hoped she could handle his rough-and-ready outdoorsy ways. “This is a miniature test to see if she really likes it, or if she’s going to pretend to like it, but either way we’re going to have a good time—or at least I will.”

On Sunday, the Fox News host posted some pictures of herself and Trump Jr. fishing in Montana on the Stillwater River. According to the report the album includes almost 10 photos including pictures of them fishing in the state's Stillwater River. From the photos, it seems like Guilfoyle has passed the test.Trump Jr. is reportedly joining forces with his father's old staff for a fundraiser in support of Republican Senate candidate Patrick Morrisey, including former White House press secretary Sean Spicer. CNBC reported the President's eldest son is expected to host the event in New York for the West Virginia state attorney general who is looking forward to taking over the seat from Democratic Senator Joe Manchin.  

Aside from their political commitments, the couple who has been previously married is slowly opening up to the world, after their relationship became known. Trump Jr., now 40, is presently in the process of divorcing his former wife, Vanessa Trump, to whom he had been married for 13 years and the two are parents to five children. Guilfoyle too has been married twice - first to California's lieutenant governor Gavin Newsom, whom she divorced in 2005, and then to interior designer Eric Villency, to whom she was married from 2006 to 2009.
