Naomi Watts is returning the favor.
"Happy Birthday to this one!!@lievschreiber ???," she captioned an adorable family pic of Schreiber wearing a sweet handprint tee while holding their two sons, 9-year-old Sasha and 7-year-old Sammy.
Though the former couple announced their split last Monday, there's clearly still a lot of love between them.
In addition to Schreiber's sweet birthday message to Watts last week, the pair's Instagram accounts are filled with family photos.
"Over the past few months we've come to the conclusion that the best way forward for us as a family is to separate as a couple. It is with great love, respect, and friendship in our hearts that we look forward to raising our children together and exploring this new phase of our relationship," Watts and Schreiber told ET in a joint statement last week.
"While we appreciate your curiosity and support, we ask the press to be mindful of our children and respect their right to privacy,” the former couple added.
