MACI Bookout's son Bentley has left fans buzzing as he looked so grown up in a pool photo with his grandmother.
Teen Mom fans gushed over the teenager and said he looks "so handsome."
On Saturday, Maci's ex-mother-in-law, Mimi Jen Edwards, posted a photo to her Instagram.
Jen stood next to Bentley in the pool and they had their arms wrapped around each other.
She wore a black one-shouldered bathing suit with a white bow on her right shoulder.
Jen accessorized with gold hoops, a gold necklace, and a smile.
Bentley's blonde hair shined as he had no shirt on in the pool.
He wore sunglasses had a big smile on his face.
"Pool Day! Love him!" Jen captioned the post.
'SO GROWN!'
One of Jen's followers commented that Bentley looked "so grown up."
Other fans posted the photo to an online forum and said how "handsome" the teen is.
"It feels so weird to see these kids grown up. Were getting old," one user said.

"Dude, how does he look like a grown a** adult?" one person wondered.
"He’s such a cute kid. It makes me feel old because he looks like a freaking adult!!" said another.
"He's turning into a handsome young man. It's crazy to see these kids grow up," wrote one user.
TIME TO DRIVE
On the June 20 episode of Teen Mom: The Next Chapter, fans saw more proof of how quickly Bentley grew up as his mother Maci, 32, was teaching him how to drive.
She said she wanted him to get some "practice under his belt" before he drove with his dad, Ryan Edwards.
Maci told him he could only drive with her, her husband Taylor McKinney, or his grandparents.
Bentley was doing well driving on the road when Maci surprised him with another test.
The Teen Mom OG star wanted her son to learn how to parallel park and she set up cones for him to drive in between - however, the teen ended up hitting a cone.
Maci let her son know that his driving wasn't perfect, but it also "wasn't terrible."
"Wow, like we really grew up with Maci and Bentley since day one and now our nephew is driving … bittersweet," a fan commented on the video that Maci posted to her Instagram.
GOLF DAY
Maci also shared a photo of Bentley and her during a golf outing last week.
"Never a bad day golfing with my boy," she captioned the post.
Maci and Bentley sat in a golf cart and smiled for a selfie.
Bentley had his cell phone in his hand and wore a navy polo shirt, tan shorts, and a tan baseball cap.
Maci sported a blue dress and sunglasses.
Fans commented once again on how grown Bentley looked.
