TEEN Mom 2 alum Chelsea Houska’s fans “can’t believe” how “grown” the star’s 11-year-old daughter Aubree looks.
The 29-year-old shared photos with her oldest child in an Instagram post on Tuesday.
Chelsea and Aubree both wore gray T-shirts, black jeans and gray boots in the snaps, while they also wore their hair down with messy buns on top of their heads.
The pair happily smiling while flashing peace signs to the camera in the first pic and they faced each other in the following photo.
The MTV alum captioned the post: “Twinning Tuesday 
”
A number of Teen Mom 2 fans took to the comments section to express their shock over how “grown” Aubree is.
One fan wrote: “Oh my gosh I Love this!!!! I can’t believe how grown up Aubree is! You are an amazing mom and are raising some incredible children!
”
Another added: “Omg aubree is sooooo big!!! 
”
A third chimed in: “Why is she so big???
”
The shocked comments continued as another person wrote: “Omgggg when did she become all grown up 
I been watching since 16 & pregnant & I feel so old now 
”
An additional fan added: “
I love it!!!! She’s getting so big! They grow up too fast.”
Some fans asked Aubree to stop growing up so fast, as another person commented: “I’m not okay with Aubree being so grown
”
A following fan asked: “When did she turn 18? 
she’s getting so big! Beautiful
.”
Chelsea shares Aubree with ex Adam Lind, 31.
The former Teen Mom 2 star is also the mother to son Watson, four, and daughters Layne, two, and Walker, five months, with husband Cole DeBoer.
Earlier this month, Chelsea posted a video montage dedicated to her husband of five years with all four of their children while Gary Allan’s classic Tough to Be Boys played in the background.
She captioned the sweet tribute: “Our kids are so lucky. happy Father’s Day.”
Cole commented on the post writing: “my heart! I love you.”
The reality alum did not share the same heartwarming post for her ex Adam, who is the estranged from Aubree.
While Chelsea regularly documents her family’s life on social media, she previously admitted that it’s difficult for her to face hate from trolls.
While speaking to Us Weekly, Chelsea shared why she doesn’t respond to her critics online.
The MTV star told the outlet: “You shouldn’t [reply] because it’s bull crap.
“Sometimes it’s nice to put people in their place if they’re saying something mean and you just want to say something back … but it’s always best to take the high road.”
Chelsea added that she has received “so much” criticism from strangers, sharing: “We’re on a show called Teen Mom. We’ve heard it all.”
