When we asked Master Shortie, 20, if he liked her, he replied coyly: "She's really nice."
She sure is — earlier, asked if she minded losing out to X Factor rivals JLS for best UK newcomer, Alex said: "No way, man, they are my brothers."
She also told us she's still friends with her former X Factor mentor Cheryl Cole — despite the fact they will be going head-to-head in the charts later this month, Alex with Bad Boys and Cheryl with Fight For This Love.
Alexandra said: "We were on the phone last night, and I was busting moves to her song. Cheryl said, Oh my God, your song's so catchy. I've been bopping to the moves'."
