With his first solo CD, "Justified," set for release this week, 'N Sync star Justin Timberlake, 21, is going into publicity overdrive.

Monday night he appears in what is being called a frank, hourlong interview with ABC's Barbara Walters.

According to snippets published in Monday's New York Post, many of his comments seem directed at former girlfriend Britney Spears, 20, including a special song he performs for Walters that's not on his new album. It's called "Horrible Woman" and includes the lines:

"So, you had your chance to be my lover/I guess you needed something more undercover/And you know that ain't cool/So let's skip the drama, call your momma ..."

Timberlake refused to say if the song was directed at Spears, says the Post.

Another subject Timberlake refused to sing about to Walters: why he and Spears broke up in the first place, and whether one of them was unfaithful.

"Honestly, I mean, you know, we're not perfect," Timberlake says to Walters. "I don't judge anybody. It's just young love ... It was a very intense relationship -- that's for sure."

Asked about the chances of a reconciliation, he replies: "That's so tough to say. I mean, at this point in my life, if you really want to know who my girlfriend is, it's the 13 songs on that CD."

Timberlake says he wants to bring home a girl who is just like his mother, Lynn Harless -- who also happens to be his manager and happened to be sitting in as Walters interviewed her son.
