ll cool j*How about that James Tood Smith, better known as LL Cool J.  He’s really is a cool dude, right?

Just ask 5 random women who ate at Mr. Chow’s in L.A. the other night … because the rapper/actor spontaneously decided to PAY for their entire dinner … and it wasn’t cheap, reports TMZ.

We spoke to the women outside the expensive Beverly Hills restaurant — and no, they weren’t actresses or supermodels … they were just 5 normal women out for a nice (and pricey) dinner.

According to them, Uncle L was eating at a table next to them, and they hit it off almost immediately — even posing for a photo with the rapper inside.

But LL decided to take his awesomeness one step further — because when the ladies finally asked their server for the check, they discovered LL had secretly covered the giant tab on their behalf.

The ladies wouldn’t say how much the check was — but five people eating at Mr. Chow’s can get real expensive, real fast.
