For eight years, Chelsea's daughter has been known as Aubree Lind. But the Teen Mom 2 mother-daughter duo has openly discussed the desire to add DeBoer (Cole's last name) to the little girl's moniker -- something the second grader fully desires -- and now, Chelsea is opening up about how she's taking steps to make it legally happen.

"I'm meeting a lawyer tomorrow to ask what the steps would be to hyphenate Aubree's last name," Chelsea divulged to her pal Chelsey during this week's episode. "She thinks it's a great idea. If you ask her, she wants [Watson] to know that's his sister."

While Adam is no longer a part of the MTV series, Chelsea later expressed some concern that it might be a challenge working with her ex to make this permanent change.

"My lawyer is going to get a hold of his attorney to see if he will agree to it," Chelsea told her friend Britnee. "But she doesn't expect to hear back from him because I think his attorney has a hard time getting a hold of him."

Potential difficulties aside (and her explaining to Britnee that filing a notion and writing up an affidavit would be the next course of action if Adam is non-responsive), Chelsea is ready to share something with her mini-me.

"I've never had the same last name as her," she sweetly declared.
