Justin Timberlake is spending his time relaxing at home, following the end of his two-year Forget Tomorrow World Tour and his Lyme disease diagnosis.

In an Instagram Stories photo posted on Monday, Aug. 4, the NSYNC alum, 44, could be seen posing in a sweatshirt that reads: “I’m not doing s— today. Mission accomplished,” as he sticks his tongue out for the camera.

Timberlake shared the news about his Lyme disease diagnosis with fans in his Instagram Stories and in his feed on Thursday, July 31.

“I’ve been battling some health issues, and was diagnosed with Lyme disease — which I don’t say so you feel bad for me — but to shed some light on what I’ve been up against behind the scenes,” the “SexyBack” singer wrote. “If you’ve experienced this disease or know someone who has — then you’re aware: living with this can be relentlessly debilitating, both mentally and physically.”

Transmitted from the bite of an infected tick, Lyme disease can cause flu-like symptoms such as headaches, joint pain, fatigue, or a fever, per the Cleveland Clinic. It’s often diagnosed by a rash resembling a bullseye around on the tick bite, and can be confirmed with a Lyme disease blood test.

The announcement came just as he ended the Forget Tomorrow World Tour. Earlier in the tour, Timberlake canceled or postponed various shows due to an ongoing back injury, bronchitis and laryngitis, and an ankle injury.

A number of the musician’s friends and family members have come out in support of him amid the announcement, including his wife Jessica Biel.

A family source told PEOPLE soon after Timberlake’s announcement that the news has brought Timberlake “clarity” and that Biel has been “incredibly supportive” of him during this time.

“He’s not 20 anymore. But when his symptoms worsened, he realized something deeper was going on,” the source said. “He pushed through for months before finally getting answers. The Lyme disease diagnosis brought clarity to a series of unexplained issues that he’s been quietly dealing with.”

As the insider explained, Timberlake’s focus is now on treatment and recovery following the conclusion of his tour.

“He’s taking it seriously. The plan is to rest, spend time with Jess and the kids and do everything he can to heal,” the family source said of the couple, who are parents to sons Silas, 10, and Phineas, 5. “He loved touring and being back onstage, but he’s also relieved it’s over. Now he can focus on his health.”
