Cameron was seen picking up Brown at Palm Beach International Airport on Saturday, according to footage obtained by TMZ.
That same day, Brown made numerous posts on her Instagram Story about her airport experience, though she did not mention any specifics regarding her travel plans.
“I just missed my plane by maybe five minutes,” she said in one clip. “So now I’m stuck at the airport for a little bit.” Alongside another clip that showed the star drinking a glass of wine, she added: “Airport is empty. But there is wine. So I’m fine.”
Reps for Cameron and Brown did not immediately respond to PEOPLE’s requests for comment.
On Sunday, Cameron’s best friend and roommate Matt James, who is set to compete on Clare Crawley’s season of The Bachelorette, shared a photo of him and Brown in Florida.
Nearly a week prior, Brown visited Cameron in his hometown of Jupiter, Florida, following his mother’s death.
A source previously told PEOPLE that despite the reunion, “Tyler and Hannah are just friends.”
“They went through this crazy ride on The Bachelorette together in front of the whole world and will always be bonded because of it. There’s no bitterness there,” the source said.
“It meant a lot to him that she came to support him in his time of need. He was able to show her around Jupiter, introduce her to his friends, and have some good laughs,” the source added of Brown’s visit. “Just being able to hang out together, smile, and take his mind of things has been really helpful to Tyler’s grieving process. It’s just what he needed.”
Cameron came in second place on Brown’s season of The Bachelorette. The pair have remained friends since Brown reunited with Cameron after calling off her engagement with winner Jed Wyatt.
“Our mother was the ultimate servant. She gave us her all until she had nothing more she could give. So we thought. Our mother gave the ultimate gift when she passed away. She was able to give more life. She was able to donate her liver and give someone another opportunity,” he wrote on Instagram Friday.
“In this very trying time for us all, we needed any positivity we could get. What helped us so much through this tough time was the hopes that our mother could give more life to someone else,” he said. “Our mother now lives on through me and my brothers but also to the man she was able to give more life to. My mom would do anything to impact the world in a positive way and these are her final ways of doing it. Love you forever momma.”
