Sisters Hilary and Haylie Duff donned matching workout gear (that made us do a double take!) as they headed to a Pilates and Piloxing class in LA, on Thursday.
The mommy-to-be has been working extra hard at maintaining her fitness since becoming preg, and it's definitely paying off, because she looks fabulous!
Duff was lucky enough to attend an exclusive private dinner party held for President Obama, when he paid a visit to LA early this week.
The actress Tweeted on Monday: "Wow just had the most interesting dinner with about 20 couples and @BarackObama !!Always fascinating to talk to such influential people!".
The private dinner Hilary attended cost a whopping $30,000 a plate, and was also a fundraiser for the President's 2012 re-election campaign.
