Andrea died two days after she was taken to the hospital on Thursday, February 27, which was the same day Tyler announced he had to cancel a Good Morning America appearance due to a "family emergency" and asked for prayers for his mother.

"She was super supportive," Tyler, 27, told the newspaper.

"But what was so amazing... she was supportive for (Hannah Brown's The Bachelorette season) and everyone else who was a part of that show but she was also supportive to the random fans."

Tyler even said Andrea once exchanged recipes with a fan of the franchise.

"She was a mom to so many," Tyler noted, adding that so many friends and neighbors showered the family with love and support following Andrea's death.

Tyler shared that Andrea was bubbly, light-hearted and definitely "could have fun," recalling the time he brought his mother to the People's Choice Awards late last year as his date.

"She got way more TV time than any of us because she was behind (country music star) Blake Shelton," Tyler joked.

"It hurts because there were so many cool things for us to do down the road, but I'm grateful I got to spend that kind of event and moment with her."

Tyler added Andrea viewed her clients as friends and went above and beyond for others.

"My mom didn't care who you were, where you came from, what you've done or anything at all," Tyler's brother Ryan told The Palm Beach Post.

"She saw everyone as the same. She just wanted to help everybody and help them out with whatever they needed help with."

Andrea's other son Austin also gushed about how his mother's words helped him get through U.S. Army training last year.

Andrea was a real estate agent at The Keyes Company who volunteered and helped raise funds for local organizations -- including the Pearl Mae Foundation, which helps low-income seniors and financially assists students entering fields in healthcare.

"Today heaven gained an angel," Tyler captioned an Instagram photo on Monday that showed three hands -- presumably belonging to Tyler and his two brothers -- holding their mother's hand in the hospital.

"We will love and miss our mother dearly. She will live on through us and through those that she has had an impact on. While we grieve, we ask for two things: First, tell those you love that you love them; and second, please let us take this time to celebrate her life in private. Thank you for all of your love and support."

Us Weekly previously reported Tyler is "utterly devastated and in shock" by his loss.

"His entire family is strong as hell but their world has been shattered," a source said.

TMZ had also obtained photos of Tyler looking somber and distraught sitting at a table in the Brass Ring Pub restaurant last weekend in Florida.

Tyler appeared to be dining with a group of loved ones, and at one point, he reportedly buried his face into the palm of his hand.

Tyler has been very open about his tight relationship with his parents and brothers ever since starring on The Bachelorette's fifteenth season last year.

Tyler brought Hannah to his hometown in Florida and gushed about the love he had for his parents. At the time, however, his father Jeff Cameron had been the one with health issues.

Tyler's reunion with his father Jeff Cameron -- who apparently "almost died" -- was an emotional one on the show. Tyler said he helped his mother a lot when Jeff was in the hospital and the former general contractor took over many of the responsibilities of his dad's business.

Once Tyler found fame, he moved away from his parents to New York City, where his modeling career apparently took off.

Andrea reportedly always served as Tyler's biggest cheerleader and supporter.

In October 2019, Tyler shared a photo of the pair and wrote that he was looking forward to being reunited soon.

"Dear Mama, I appreciate you. I love you. I need you," Tyler captioned a sweet photo of them smiling. "See you soon."

Andrea also flew out to New York in November 2019 to watch her son cross the finish line in the New York City marathon.

Tyler announced in January he'll be serving as the host of Barkitecture, a new short-form video series about building elaborate dog houses that will be available on the new mobile streaming service Quibi, which will provide users with "quick bites" of content and entertainment and be launched on April 6.

Each episode will feature Tyler and his co-host, Brooklyn-based interior designer Delia Kenza, working with different dog owners to build customized, luxury houses for their pets.

As far as Tyler's dating life goes, he was most recently linked to Kylie Jenner's best friend Anastasia "Stassie" Karanikolaou and supermodel Gigi Hadid before that.

Tyler finished as the runner-up on Hannah's season of The Bachelorette when she chose to accept a marriage proposal from aspiring country singer Jed Wyatt instead.

But after Hannah and Jed split, the former beauty queen asked Tyler out on a date during the reunion special for The Bachelorette, which aired in late July 2019.

Hannah and Tyler's potential for reconciliation, however, ended shortly after they spent one night together in Los Angeles in early August and then Tyler moved on with Gigi.
