Rachel McAdams shows off her cheeky side in sheer gown post-baby

The 39-year-old actress needs no time bouncing back post giving birth!

Rachel McAdams made her first red carpet appearance since giving birth to her son with boyfriend, Jamie Linden. The movie star stunned at the 'Disobedience' premiere at the Tribeca Film Festival with co-star, Rachel Weisz by her side. While Weisz went for a more conservative dress with slight cut-outs on the shoulders, McAdams opted for a romantic plunging floral gown from Giambattista Valli Spring '18.

The sheer tulle skirt left little to the imagination, showing off a cheeky glimpse of McAdams envious physique. With her hair pulled back into a beachy updo and subtle pink lips, it's safe to say she's never looked chicer.
