Lindsay Lohan SNL party blonde Lindsay Lohan SNL party blonde

After hitting the Saturday Night Live stage this weekend, Lindsay Lohan and her mom Dina hit the town for some late-night fun in the Big Apple.

The mother-daughter duo, both rocking platinum locks, were happy to great the enormous crowd that gathered outside the studio.

We're still on the fence regarding Lindsay's SNL performance, but regardless, she did seem to be 100% with it ... which is a start.

Also joining in on the after-party ... Real Housewives of New York star Jill Zarin and actor Paul Rudd.
