Jennifer Lopez (search) and husband Marc Anthony (search) will open the President of Latin Music Festival (search). The three-night event runs Friday through Sunday.

It will be the first time that Lopez performs onstage in the Dominican Republic. Anthony has performed four times in the Caribbean country.

Lopez's participation shows how important the festival has become to Latin and Caribbean artists and "the affection and respect she has for her roots," said festival spokeswoman Maribel Hernandez.

The sixth biennial President of Latin Music Festival will be held in Santo Domingo's Felix Sanchez Olympic Stadium. Some 150,000 people are expected to attend.

Spanish pop-singer David Bisbal, Puerto Rican reggaeton singer Daddy Yankee and Dominican merengue singer Sergio Vargas will perform on Saturday and Sunday.
