Tim Tebow's taking his upcoming wedding as serious as one of his workouts … 'cause the ex-Heisman Trophy winner was sweating his face off practicing his moves with his fiancee!!
The former NFL first-round pick showed off his waltzin' skills with Demi-Leigh Nel-Peters … and he also flashed a healthy sweat that could be seen through his pink shirt.
Don't worry … Demi-Leigh — Miss Universe 2017 — didn't seem to mind the perspiration … in fact, she shouted out the guy for improving!!!
"Getting better," she wrote … "one step at a time."
Unclear if the couple is planning on making this their first dance at their wedding … but the celebration appears to be coming up soon.
Remember, the two got engaged back in January … and their posts about their upcoming wedding have REALLY started to heat up.
Which means … only a few more weeks left with that v-card, Timmy!!!
