Jessica and Eric arrived at the premiere in support of Jessica's brother-in-law Evan Ross, who is married to her younger sister Ashlee.
Evan celebrated his role in The Hunger Games: Mockingjay Part 1 by taking the gang along to the screening, and it turned out to be a right family affair, with Evan's superstar mother Diana Ross and his sister Tracee also showing their support.
Jessica and Eric, who are parents to children Maxwell and Ace, only had eyes for each other as they posed for photos.
The loved-up couple, who tied the knot in sunny California in July, seemed to enjoy their night off from parenting as they indulged in the PDA.
Dukes of Hazzard star Jessica also looked smokin' hot in a slinky one-shoulder gown with a thigh-high split.
Meanwhile, Ashlee couldn't resist giving her man a little kiss too, and she was seen sharing a smooch with Evan as they also posed for photos.
'Pieces of Me' singer Ashlee married Evan in Connecticut on 30 August, with the nuptials taking place at Diana's hone.
