Sienna Miller and her mom Jo donned the latest in Hawaiian hoedown chic while partying in Niagara Falls, Canada Monday night.

The Millers danced the night away at a local casino and were joined by Sienna's "Camille" co-star - and rumored new beau- James Franco.

While the mom and daughter duo opted for matching green floral blouses and pink cowboy hats, James kept it cool in jeans and a blazer.

Sienna may have topped Vogue Magazine's Best Dressed list, but in this getup she has more in common with Anna Nicole than Anna Wintour.
