Reese Witherspoon refers to Sofia Vergara as her "work wife".
The actresses are filming new movie 'Don't Mess With Texas' in which they play a police officer and a prisoner on the run together, and Reese shared some snaps of them on set yesterday (06.06.14).
Alongside one picture of Sofia leaning in to apply her friend's make-up, Reese wrote on Instagram: "Thanks for the makeup @SofiaVergara Now can you do my hair?"
Sofia - who is in New Orleans with Reese for the shoot - posted a similar photo, with the caption: "Makeup emergency, NoLa Set! @RWitherspoon don't panic!"
Reese has been helping her co-star get over her recent split from fiance Nick Loeb while they shoot the film, which the failed politician reportedly begged his former partner to help him get a part in.
Sources say the 38-year-old had been trying to take advantage of Sofia's fame for a while.
An insider said: "He's always tried to use her success to make himself successful. I think she's finally started to see him as the opportunist he really is."
