Jennifer Garner and her boyfriend John Miller aren't planning to have any more children even if they get married, despite what rumors are claiming.

Last month, OK! magazine claimed that Garner and close pal Reese Witherspoon were both expecting a child. At the time, the "Big Little Lies" star poked fun at the baseless rumor, asking Garner on Instagram if she wanted to raise their "imaginary babies" together.

On Wednesday, Garner also addressed the pregnancy speculations, putting them to rest once and for all. During her appearance on "The Ellen Show," the "Love, Simon" star told host Ellen DeGeneres that she had no more plans to expand her brood at her age, which is 47.

"We've wrapped it up, we're not doing it," she stressed.

Garner has three children, 13-year-old Violet, 10-year-old Seraphina and 7-year-old Samuel, all of whom she shares with ex-husband Ben Affleck. And though he hasn't talked about plans to tie the knot or have another child, Garner's boyfriend, who is a divorcee as well, also has two kids from his previous marriage with ex-wife Caroline Campbell.

Garner said that it had been awkward to see the "news" of her supposed pregnancy being splashed on the cover of a tabloid at a grocery store.

But while she may not be planning to have any more children, Garner joked that her friend Reese might not have the same mindset.

"Reese on the other hand, she might be ... she's definitely pregnant," she jokingly said. "She's having twins!"

The two actresses have been unfazed by the pregnancy rumors and even joked about it in a video last week. In a video posted on Garner's 47th birthday, Witherspoon tells the "Alias" alum that they shouldn't be drinking since they were supposedly pregnant while they were sipping on wine. She added that this was a "bad idea."

Witherspoon jokingly added that her "baby bump" is just a burrito, and Garner claimed that hers was a "slice of an avocado."

During her Wednesday TV show appearance, Garner also opened up about the mishap she caused during her son Samuel's 7th birthday in February. At the time, she had surprised her son by dressing up as Astrid from "How To Train Your Dragon," which was the theme of his party.

However, her little boy had been unimpressed by his mom's efforts despite being a huge fan of "How To Train Your Dragon."

But while her children may not think she's cool, Garner is still considered one of the most beautiful people in Hollywood. The actress graces the cover the People magazine's new Beautiful Issue 2019, looking stunning in a floral outfit and boots.
