The 'Blue Bloods' star shared the experience on social media on Wednesday.
Donnie Wahlberg is the man!
The New Kids on the Block singer surprised a young man with a FaceTime call after he didn't believe his mother and uncle met him at one of his Wahlburgers resturants on Wednesday.
"This guy Nate didn't believe his mom and uncle were meeting me at @Wahlburgers, so I facetimed him on her phone to prove it -- his reaction was everything! Nice to meet you too Nate! Good luck at grad school!" Wahlberg, 47, wrote on Instagram alongside a screenshot of the call.
The picture shows the Blue Bloods star smiling as Nate is covering his mouth in disbelief.
Wahlberg is known for being great to fans. Last month, after dining at a Waffle House in Charlotte, North Carolina, the singer tipped $2,000 on an $82 meal, saying "when the staff treats me like a king, you better believe I treat them like queens!"
