First Lady Melania Trump has an older sister, Ines Knauss, who also lives in New York City and has been able to maintain a low profile while her sister has been thrust into the spotlight.

According to the New York Post, the sisters are best friends and the 46-year-old First lady considers Ines, 48, to be a confidant.

“They are very close,” Palm Beach philanthropist Audrey Gruss told the Post, who met Ines in 2005 during a fundraiser at Mar-a-Lago. “She struck me as a lovely person, and extremely creative.”

Here’s what you need to know about Melania Trump’s sister, Ines Knauss:

They changed their last name to Knauss, from Knavs.

“She really wanted to be in fashion but didn’t know how to break in,” photographer Ale de Basseville told the Post. “Ines wasn’t like the other girls you would meet there, who behave like queens. She was really polite and very mellow.’

But she was following along, her Facebook shows, proudly posting photos of Melania alongside Donald Trump, and posting about the results of the Republican primaries and November election.

“Ines is a very dedicated sister,” fashion designer Luisa Beccaria told the Post. He said he saw the family support Melania gets from Ines after Barron Trump was born in 2006.

“I realized that Melania was very close to her family when I saw them all there supporting her after Barron’s birth,” Becarria told the Post. “Melania had all the professional help she needed at that point, but it was her sister she trusted.”
