Nicole Murphy -- Another Day, Another Date

If Nicole Murphy were in the NBA she'd lead the league in rebounds.

Murphy and some young mystery man hit up Moonshadows in Malibu for lunch Saturday just days after reuniting with Michael Strahan for lunch Thursday in Beverly Hills.

And of course ... there's very handsome former NBA star Jim Jackson whom she was banging in Puerto Rico.

As we previously reported ... sources close to Strahan and Murphy told us there's a possibility for reconciliation -- so it's feasible this date was just a friendly meal.

These girls ain't loyal ... or are they?
