is erasing the evidence of her marriage to Seal.
In 2008, Klum, 40, referred to an abstract permanent design
on her right inner arm as a commemoration of vow renewal with her singer husband.
"It was our fourth wedding, and we wanted to have our names tattooed together," the America's Got Talent
judge – who is now dating
her bodyguard, Martin Kirsten – said of her body art at the time. "So it's my husband's name and our three children – their initials, in the [three] stars."
Now, Klum, who filed for divorce
from Seal, 50, in April 2012 after seven years of marriage, "is in the process of getting her tattoo removed," a source tells PEOPLE.
As evidenced by recent photos showing the lightened ink on Klum's arm, "she's been through a few treatments," says the source. "The stars with her children's initials will stay intact."
