Celebrity lawyer Michael Avenatti — who is representing porn star Stormy Daniels in her lawsuit against President Trump — has now inserted himself into the border separation fight.

Avenatti tweeted Tuesday that he’s representing a migrant mom who he says was separated from her 6-year-old old son in Texas — and hasn’t seen him in two weeks.

“They told her he was being taken for a ‘bath’ & would be brought right back,” Avenatti tweeted.

“They separated them in Texas and shipped him to Arizona. He was crying hysterically and calling out for his mom as they grabbed him and dragged him from her for his ‘bath.’ She sobbed uncontrollably as she told the story. This is not our America,” he added in a second tweet.

The attorney, who has worked on Democratic political campaigns in the past, also shared a touching letter from the mom, named Levis, to her son, Samir.

“I lament what is happening, my son. This separation hurts my soul. But I want you to know that I haven’t abandoned you. Mama is here,” she writes in Spanish.

“When I wake up, the first thing I do is think about your eyes and the feel of your arms … in the morning and the feel of your kisses, my son. How much I miss you, Samir.”

When they’re reunited, she promises to take him to the aquarium.

“It’s what you always wanted to see, the animals, the dolphins, the fish, the penguins, even though you are scared they will eat you. Hahaha,” she writes.

“Soon, very soon, we will see each other again.”

Migrant kids are being separated from their parents under the Trump administration’s controversial new “zero tolerance” policy to prosecute all adults who cross the border illegally.

Avenatti also set up a crowdfunding campaign Monday to cover the costs of getting moms out of immigration detention and to reunite their families, which had raised more than $70,000 as of Tuesday afternoon.
