'American Idol' now down to top 3 with one week left before finale

The "American Idol" Top 5 became the season's Final 3 after a semi-final round filled with fan-favorite Disney hits. 

"They're all number ones at this point," said Judge Lionel Richie 

"American Idol" is now down to 18-year-old Iam Tongi, 21-year-old Megan Danielle and 18-year-old Colin Stough. 

On this Disney Night, also celebrating Mother's Day, two of the judges say Tongi may be the one to beat 

Tongi wore his parents close to his heart in a special necklace. 

If the crowd's enthusiasm says anything, that might be true," said Katy Perry. 

The show said its goodbyes to We' Ani from New York and Zachariah Smith from Mississippi 

This is the new chapter to my new life. I feel like I was born to be on stage," said Smith. 

The three-hour "American Idol" season finale airs Sunday May 21 live from Hollywood.
