Justin keeps his cool on being quizzed by Heidi Klum

London, June 9 (ANI): Teenage heartthrob Justin Bieber resisted taking a peek while giving an interview to Heidi Klum, who wore a boob-revealing frock.

The 18-year-old singer remained cool as he was quizzed after performing on Germany's Next Top Model telly show.

After getting a congratulatory hug, the 'Baby' hitmaker perched himself on a seat next to the legendary supermodel.

Bieber is currently promoting his new album 'Believe' and will return to Germany next year to play a series on concerts, the Sun reported.

"Great time in Germany. Can't wait to see you all again on the #BelieveTour next year!" he tweeted.

This weekend Bieber returns to the UK to appear at Capital FM's Summertime Ball. (ANI)
