AceShowbiz - Kirsten Dunst and fiance [Jesse Plemons] have reportedly named their baby boy Ennis Howard. The actress, 35, welcomed her first child on May 3 in Santa Monica, California, according to a birth certificate obtained by The Blast.

Neither Kirsten or her "Fargo" co-star Jesse's representatives have commented on the reports as yet. The arrival of their son comes three months after the actress confirmed her pregnancy in the Fall/Winter portrait series for fashion label Rodarte, co-founded by her best friends, sibling designers Laura and Kate Mulleavy.

The couple began dating in 2016 after meeting on the set of the FX series, where they played a married couple. News of their engagement was reported in January last year, when Kirsten was spotted with a ring on her engagement finger at the Golden Globe Awards.

Back in June, "The Beguiled" star explained her priorities had changed since meeting Jesse. "I'm at a stage in my life where I'm like, 'I've been working since I was 3. It's time to have babies and chill,'" she told Britain's Marie Claire magazine last year.

"I wasn't one of those 'I need a baby!' people until my goddaughter was born. I love her so much. That love is just like... you can't experience that unless you have a kid," she added.

The couple has still yet to tie the knot, but Kirsten admitted they were having fun using Pinterest to brainstorm ideas for the wedding. Along with work and prepping for the birth of her first child, Dunst has been busy with wedding planning.

"It's really fun, and because we create it together from the beginning, it's a really nice thing to do together," she revealed on "Live with Kelly and Ryan" back in June. "It's going to be so personal and fun. We're having a really good time."
