Meryl Streep and Cher, two icons, came together for an iconic moment in time when they kissed on the red carpet this week.

At the premiere of the film “Mamma Mia! Here We Go Again” in London on Monday, the stars gave each other a peck on the lips.

The iconic Hollywood costars — who also worked together on 1983’s Silkwood and 2003’s Stuck on You — were in London promoting Mamma Mia 2 when they pulled the cheeky move on the blue carpet. The musical — inspired by the ‘70s Swedish pop group ABBA — also stars Amanda Seyfried, Lily James, Pierce Brosnan, Dominic Cooper and Christine Baranksi.
