White Lotus actress Alexandra Daddario, 36, put on a very busty display on Thursday as she enjoyed a dip in the river with sister Catharine, 29, in Louisiana. 

The duo donned matching mint leopard print swimsuits for the afternoon, as they lounged on the riverbank and enjoyed the sunshine.

Later the sisters showed off their impressive skills as they paddle-boarded together, flaunting their fantastic physiques in the process.
