More than one month after Tom Hanks and Rita Wilson‘s son Chet Hanks reportedly went missing, the 25-year-old has resurfaced on social media.

Over the weekend, LA-based celebrity hairstylist and makeup artist Bella Cheveaux posted a photo on Instagram of what appears to be herself posing with Chet.

However, Cheveaux’s caption on the snapshot includes a reference to the popular hashtag #ThrowbackThursday, suggesting the photo is not a new image of Chet and rather an old picture that she has just now reposted.

Last week, Star Magazine reported Tom, 59, and Rita’s eldest son had disappeared after posting a cryptic message on Instagram in July. “I’m not gonna be on Instagram for a while… Getting the f**k out of Dodge for a min… Gonna go get my mind right,” Chet wrote on the site.

“A month went by without a word from Chet — not even a single phone call to his family or friends. It’s like he’s fallen off the face of the Earth,” a source close to the Hanks family told the magazine.

Rita, 58, and Tom’s son has struggled with substance abuse since age 16 and checked into a rehab facility at his parents’ request last winter. The couple — who married in 1988 — are also parents to a younger son, Truman Hanks, 19. The Forrest Gump actor additionally has two kids, son Colin Hanks, 37, and daughter Elizabeth Hanks, 33, from his previous marriage to actress Samantha Lewes.
