Pam recalls first meeting Gaga on a very "somber" day. "My mother had just passed away and [Gaga] came , and she was just the sweetest thing that ever was," she said. "When [Taylor] said she's coming, I said, 'No, this isn't a good time.' And she came, and she was a sweetheart."
Taylor's mom seems to love Gaga, 29, as much as he does. "I loved her from the moment I met her," Pam added.

As for the couple's wedding day, the mother of the groom says she isn't planning on wearing a Gaga-esque dress. Rather, Pam is looking for something more "subdued."
Taylor also spilled some secrets about his home life with Mother Monster. While he wouldn't admit whether Gaga has a thing for firemen, he did say he fantasizes about wearing his fireman costume home.
"I kind of have this dream that's not a dream, but when we are done with our run, I kind of want to yank all my character's gear -- my bunker gear, my coats," the 34-year-old actor confessed. "So, I hope they don't have a problem with that."
