The singer, who sang backing vocals for Faith before recording her own album, described her as "fabulous all the time".
She told the Daily Star: "I'm going to present her with a personal vinyl copy of my album.
"She's just really smart, so generally being around her felt like I was learning ways to be a stronger woman."
La Havas continued: "She always manages to be completely fabulous all the time while being super smart, dedicated and hard-working. And she taught me to dress for my shape. Heels make everything better."
The 22-year-old's debut LP Is Your Love Big Enough? is currently battling for number one this Sunday with Newton Faulkner's Write It On Your Skin.
