Lil Wayne -- KICKS IT WITH REAL MADRID ... After Meeting with Ronaldo

Lil Wayne hit up the Montage Hotel in Beverly Hills this week to chat business with Cristiano Ronaldo -- and wound up kicking it with the entire Real Madrid soccer team ... TMZ Sports has learned.

As we previously reported, Weezy's starting his own sports management company and Ronaldo is Client #1 -- so it's no coincidence they hooked up while they were both in L.A.

Sources close to the situation tell us Wayne and Ronaldo met for about an hour -- and on his way out of the hotel, he was bombarded by Ronaldo's ultra-famous teammates.

Among Wayne's famous fans who asked for pics -- Sergio Ramos, Jese' and Pepe.

According to our sources, the players had JUST come from the practice field ... and were getting ready to head to their next destination -- Dallas.

It's unclear if Weezy has any of Ronaldo's teammates in his sights to add to his client roster -- but if things work out with Ronaldo, you can expect a line around the block.
