Ben Affleck and Jennifer Lopez are engaged!

Hollywood power couple Ben Affleck and Jennifer Lopez are engaged — again!

The 52-year-old singer and actress announced the happy news in a video message to her fans via her fan newsletter.

In the video, a tearful Lopez showed off her green diamond ring and said: "You’re perfect.”

Earlier this week, the couple sparked engagement rumours when Lopez was photographed wearing a ring on her wedding finger while out and about with her daughter, Emme.

Lopez and Affleck rekindled their romance almost two decades after calling it quits, ending their first engagement in 2004.

After their split, Lopez tied the knot with singer Marc Anthony, giving birth to twins Emme and Max while Affleck married actress Jennnifer Garner, where they share three children; Violet, Seraphina and Samuel.

Prior to the return of "Bennifer”, a nickname fans coined for the couple, Lopez was engaged to baseball player and businessman, Alex Rodriguez.
