First and Last Days of the previous week using MySQL

A bit of a challenge here, trying to get the first and last day of the previous week (Sunday and Saturday).

SELECT 

       Date_add(Date_add(Now(), INTERVAL -            Weekday(Now())-1 day),INTERVAL -7 day) 'Sunday', 

       Date_add(Date_add(Date_add(Now(), INTERVAL -    Weekday(Now())-1 day), INTERVAL 6 day),INTERVAL -7 day) 'Saturday';
