VIDEO : Search Called Off For Pop Star Missing From Cruise Ship

A search for missing German pop singer Daniel Kaiser-Kueblboeck has been called off.
On Sunday, Kaiser-Kueblboeck jumped overboard an Aida cruise ship en route to Newfoundland.
An extensive air and marine search was launched by the Coast Guard.
CNN reports, the search was ended because of the "short survival time" in water temperatures at this time of year.
Aida cruise company said it was "deeply concerned about the tragic incident."
Kaiser-Kueblboeck rose to fame in 2002 as a contestant on the reality TV show "Germany Seeks The Superstar."
