Palmer, 83, seems quite smitten with the 20-year-old beauty, saying in an interview with Sports Illustrated's Golf channel, "Did you see this?" and then holding up the magazine's swimsuit issue with Upton on the cover.
"She's coming here. Did you know that?" Palmer said, a reference to his Bay Hill Club & Lodge.
He then glanced again at the cover, which features Upton in Antarctica, clad only in a polar jacket and bikini bottoms, and said, "I better cover this up," before placing some papers over the racy photo.
Lisa Benson, Upton's manager, arranged the "date" -- Benson's father used to play golf with Palmer, and Upton’s parents are huge fans of the Hall of Famer.
Based on those connections, Upton decided to visit Palmer in Florida. In addition to their dinner date, she plans to see the work he's doing with hospitals. His foundation provides support to an Orlando area children's hospital that is named after him.
This isn't the only “date” Upton has planned. The Sports Illustrated swimsuit model may also go on a date with Jake Davidson, a Los Angeles high school student. Davidson made a two-minute YouTube video asking Upton to be his prom date.
“You had me at hello. You're the ying to my yang, I'm Jewish, 5'9" on a really good day -- and I can't dance at all,” he said in the video, which has received more than 100,000 views. “You're Christian, 5'10", and that Cat Daddy video should have won an Oscar for best short film. You could say this is destiny.”
Upton replied on Twitter to Davidson’s request, telling him he could call her “Katie,” and that she will join him if her schedule allows.
