Double trouble!
Jessica Simpson and pregnant Ashlee Simpson stole the spotlight while attending the special preview of "The Gleason Project" at ZEFR Warehouse in Venice, California on Thursday.
Jess looked super sexy in a sleek, black and white sleek, while her expecting sis masked her big baby bump in an oxblood dress and a black jacket.
The mother-of-two's hubby, Eric Johnson, also snuck in a funny photo bomb behind!
We love that Jess and Ash still make time for each other in between their busy schedules. It definitely seems like the 34-year-old has her hands tied these days with her two adorable children, Maxell and Ace, in addition to running her fashion empire.
And Ashlee's been equally busy these days, too, hitting the gym and spending time with her hubby Evan Ross.
The pair -- who tied the knot last August -- announced that they were expecting their first child together in December. This will be the second child for the 30-year-old who shares a son, Bronx, with ex-hubby Pete Wentz.
We can't wait to see Ashlee's baby girl when she gets here -- what do you think about the Simpson sisters' red carpet appearance? Tell toofab in the comment section below and click "Launch Gallery" above to see more cute celebrity siblings!
