The Oscar-winning actress hit the red carpet at The Change-Up premiere, despite not actually being in the movie, and got the flashbulbs popping in her elegant black Lanvin jumpsuit.
The starlet teamed her all-in-one with strappy black sandals, hooped earrings, embellished gold bracelets and rosy-hued makeup.
The pair became close pals after starring in 2009 rom-com The Proposal together.
Ryan Reynolds - who always manages to scrub up pretty well on the red carpet - stars in The Change-Up alongside Olivia Wilde, Jason Bateman and Leslie Mann.
