Jennifer Aniston Says She Was Intimidated By 'Mother's Day' Co-Star Julia Roberts!

Jennifer Aniston and Julia Roberts both rock blazers as they hit the red carpet at the premiere of their latest film Mother’s Day held at the TCL Chinese Theatre IMAX on Wednesday (April 13) in Hollywood.

The 47-year-old actress and Julia, 48, were joined at the event by their co-stars Jack Whitehall, Hector Elizondo and Loni Love, as well as Bob Saget, John Stamos, Perrey Reeves, Kelly Kruger, Mel B and her hubby Stephen Belafonte, Jillian Michaels and Heidi Rhoades, Yvette Nicole Brown, Kate Flannery, Lauren Ash and Heather McDonald.

“Yeah! Because it’s Julia Roberts! Oh my gosh,” Jennifer expressed when admitting she felt intimidated working with Julia on set (via ET). “It’s just a different thing when you get to work with them and then you’re doing what you both do, [but] together. I even flubbed in the first take and called her Julia!”

FYI: Jennifer is wearing an Anthony Vaccarello outfit, Christian Louboutin shoes, Eva Fehren jewelry, and holding a Jimmy Choo clutch. Julia is wearing Rag & Bone ensemble paired with Giuseppe Zanotti pumps and Jack Vartanian earrings. Perrey is wearing an H&M dress.
