The celebrity couple are the face of River Island's collaboration with War Child, as they launch a collection of Come Together t-shirts designed by River Island to raise awareness and money.
In the picture the former Made In Chelsea star Millie and her rapper husband Professor Green mirrored the pose of the famous Lennon and Ono, who staged two week-long bed-ins for peace in 1969.
The t-shirts are an exact replica of one John Lennon wore in 1971 to the Cannes Film Festival. The t-shirts for men, women and children feature an original 1969 design by Rob Rose and Arnie Goodman.
The t-shirts, priced at €25 and €10 for children are on sale at selected River Island stores and online from tomorrow (see here). All profits will go directly to War Child, providing life-changing support to those in some of the worst conflict-affected places in the world.
