Jenni Rivera’s reality series will debut its third season on NBCUniversal’s mun2 network in April, just several months after the performer died. New episodes of “I Love Jenni” will include footage shot in the weeks before she was killed in a plane crash in northern Mexico; subsequent episodes will show her grieving family, including Rivera’s children — Chiquis, Jacqui, Michael, Jenicka and Johnny — as well as her sister Rosie.
