Oprah’s parade of musical newsmakers isn’t over yet.

Last week, the talk show queen welcomed a visit from pop star Lady Gaga. Tomorrow, she’ll play host to two names quite familiar to the tabloids.

Adam Lambert, who caused a big stir after his controversial American Music Awards appearance, will address that kiss, talk about Simon Cowell’s American Idol departure and perform for the Chicago audience.

Another personality familiar with the British judge will also be chatting with Winfrey this Tuesday. Susan Boyle - who was discovered on Cowell’s other show, The X Factor - will discuss her highly-publicized breakdown and her record-breaking debut album.
