Bronny James couldn't help but show love under Parker Whitfield's new social media post on Sunday ... dropping a flirty comment in the replies for all to see.
James and Whitfield first sparked dating rumors when they were spotted at the Paris Olympics together earlier this month ... with the two catching LeBron and Co. during their epic gold-medal run.
If making an international trip to France wasn't telling enough, Bronny's latest Instagram activity pretty much confirms they're an item.
