Drew Barrymore, who is engaged to Will Kopelman, is reportedly converting to Judaism because her fiance and his family are Jewish.

The dramatic show of devotion has shocked Hollywood but this shows that she is head-over-heels for him.

The couple are due to marry later this year in what is now expected to be a very religious ceremony.

According to In Touch, she has been getting a lot of help and information on the subject from her good friend Adam Sandler.

"Those two absolutely adore each other, so it only made sense to Drew that he will be right by her side playing an important role at her wedding," the Daily Mail quoted a source as saying.

Apparently, the 36-year-old star has also told Kopelman's family that she wants to raise her children in a Jewish household.

However, Barrymore's representative has denied the actress' plan to convert. (ANI)
