R&B singer Cassie was forced under cross-examination Thursday to read to a jury her sexually explicit messages with former boyfriend Sean “Diddy” Combs, some of which showed her expressing enthusiasm for encounters with other men at Combs' behest that she previously testified she “hated doing.

Ventura is the prosecution’s star witness, and her testimony Tuesday and Wednesday alleging her ex-boyfriend Combs physically and sexually abused her is key to the charges against the hip-hop mogul.

Ms. Ventura said she participated for days at a time, sometimes without sleep. “Something that Sean wanted to happen, that’s what was going to happen,” she testified.
