Hollenius at the Wedding Reception/First Meeting Karel

What did Hollenius call Christine at the wedding reception when he first met Karel...."my little YULAH???". I was trying to find the exact expression or possible term of endearment, but, imagining it's a little German or Russian term of endearment, I couldn't find it anywhere, as I'm not sure I'm spelling it correctly.

Anyone know what exactly Hollenius called Christine, while he softtly squeezed her cheek at the reception?
