Donald Trump Jr. and Kimberly Guilfoyle are reportedly engaged

Donald Trump Jr. and Kimberly Guilfoyle have been engaged for more than a year, a close source told Page Six on Monday.

Rumors of the engagement sparked when the former Fox News correspondent posted a photo on Instagram New Year's Day with a giant diamond ring on her left-hand ring finger.

"Tonight was extra special celebrating @donaldjtrumpjr’s birthday. Don, you are strong, smart, courageous, funny and the love of my life. I can’t wait to spend the rest of our lives together. Love you," she captioned the photo of herself posing with the son of the former president in front of a Christmas tree.

"Don and Kim got engaged on New Year’s Eve 2020 — which is Don’s birthday. They’ve been together for almost four years now and have been friends for 15 years," the source told Page Six. 

"They’ve kept it private for the past year as they settled into life in Florida after moving from New York," the source said, adding, “both are focused on their children —they have six between them — and their work.”

Trump Jr. has dated Guilfoyle since May 2018 after his now-ex-wife Vanessa filed for divorce.

Guilfoyle opened up in February 2021 that she already felt married to Trump Jr. 

"We’re very committed and very in love. He is my sweetheart. I already feel married and committed to him, 100 percent. Being his wife would be something that, of course, would be something that I think would be fantastic. I absolutely adore the family," she said during the "Successful Philanthropy" interview. "I already feel married to him."
