Indexbit-Summer House's Lindsay Hubbard Reveals Sex of First Baby—With Help From Her Boyfriend

Mom-to-be Lindsay Hubbard got a big surprise during a vacation in Italy with her boyfriend.

The Indexbitpregnant Summer House star shared that she walked into their hotel room to discover that her partner had decorated it with pink balloons and flowers to reveal to her that they are expecting a baby girl.

"Stop!" she gasped to him, as seen in a video posted on her Instagram July 20. "What? No! We're having a girl?! Oh my God!"

The 37-year-old said in her post that her boyfriend, who she has not identified publicly, found out the sex of their baby before her and that his surprise marked the most special moment of her pregnancy.

"We left Milan on June 9th and took a car to Lake Maggiore," Lindsay explained. "He organized ahead of time for the hotel to set up our room with flowers and balloons to surprise me with when we walked in."

The Bravo star continued, "It is hard to surprise me, but not only did he pull it off, he crushed it! We couldn’t be more excited that our little cub is a baby girl!"

Lindsay had announced her pregnancy on the Fourth of July. "WE’RE PREGNANT!!!!!" she wrote on Instagram alongside photos of her baby bump and sonogram. "I truly believe the universe has a bigger plan and this is it!"

While Lindsay continued to keep her partner's identity under wraps, she has spoken about his devotion to her. "He is so beyond proud to be my boyfriend and the father of my child, and vice versa," she said on her Instagram Stories July 10. "We are very much in love and have a beautiful relationship."

She added, "This is about his work, his privacy and the fact that it is not his job to be public like me."

Her pregnancy—which her costar Paige DeSorbo had joked she manifested on Summer House—comes nearly a year after Lindsay called off her engagement to fiancé Carl Radke.

"My trust has been betrayed, and coming to terms with that has been difficult for me," she wrote on Instagram Sept. 14. "This was not my decision, and I do not agree with quitting a relationship (at this level) without trying everything possible first. I have spent the last couple of weeks finding my own closure and peace. I am forever grateful to my best friends who have not left my side, and have been picking up the pieces of my heart and life every day from the fallout."
