The Real Housewives of Beverly Hills star told E! News that raising her two sons with Rimes and ex-husband null is "just frustrating."
"But coparenting is something we have to do and it's you know, I don't really want to overshadow Yolanda [Foster]'s day talking about silly drama."
Glanville was on hand for her costar's special day of being granted her American citizenship after lots of hard work.
"I'm so proud of her and I was with her while she was studying and she had a lot of questions, I just wanted to support her," she said.
But noticeably absent from the oath ceremony were the ladies' costars.
"I have no idea [where they are]," Glanville told E! News. "I can only speak for myself."
And now that Foster is officially an American citizen, celebration is in order.
But not so fast, Glanville told E! News, "I was joking that we'd go have some apple pie and a hamburger. She's not feeling great, so she just wants to rest, so I have to respect that, and I just wanted to be here to support her."
Congratulations are in order for Mrs. Foster!
