It appears Logan Paul has a new lady in his life -- the YouTuber/boxer was spotted out with Sports Illustrated swimsuit cover model Nina Agdal in London this week ... and we're told they were packin' on the PDA.
Sources tell TMZ Sports the 27-year-old social media star and 30-year-old beauty were getting cozy at Novikov on Wednesday night ... and at one point, they even shared a kiss as they sat at a table with friends.
We're told Logan and Nina tried to keep it lowkey as they left the restaurant .
