February 18, 2010 (BARNSTABLE) A Cape Cod teenager makes the top 24 of American Idol.
Siobhan Magnus of Marstons Mills will now perform live in the next round on Tuesday night.
The 19-year-old and her family knew she had advanced- but were prohibited from telling anyone until the show aired last night.
Tuesday, the girls will compete live, with the guys going on Wednesday.
That means the public will get to start voting, because four will be eliminated on Thursday.
