Their friendship fell apart when Victoria did not stand by Cheryl when she was cheated by ex-husband Ashley Cole in 2010.
However, things seem to have changed now, reports dailystar.co.uk.
"Posh has offered Cheryl an olive branch since moving back to London. She e-mailed inviting her and boyfriend Tre to dinner and Cheryl accepted," a source said.
"A lot of time has passed since they fell out and they both want to move on," the source added.
