Jennifer Garner-Ben Affleck Update: Garner Debunks Pregnancy Reports While Affleck Sparks Dating Rumors With Mystery Blonde

Jennifer Garner refuted reports claiming that she is pregnant with her fourth child with ex-husband Ben Affleck, OK! Magazine reported. The news comes just after reports surfaced that Affleck may be dating a new mystery blonde.

The "13 Going On 30" actress' representative told OK! Magazine that rumors of her pregnancy are "completely false." The comments came just after a Hollywood Life claimed that Garner is "100% pregnant."

"Ben has been spending lots of time with Jen and the kids at the family compound," a source told Hollywood Life, adding that the duo is expecting their fourth child together. Affleck and Garner have three children, Violet, 9, Seraphina, 6, and Samuel, 3.

The couple announced in June that they are ending their 10-year marriage.

"Jen is interested in saving her marriage for her kids," the source told Hollywood Life. "She is taking it day-by-day and Ben has really been a changed man of late, so it might just work out now that the dust has cleared."

Meanwhile, according to another report, Affleck has been moving on from his split with their family's former nanny Christine Ouzounian.

Affleck was recently spotted with a new girl at The Beverly Hills Hotel, OK! Magazine reported.

"He pulled up in his new muscle car, a Dodge Challenger Hellcat, with a hot blonde in the front seat," the insider reportedly said. "They were both dressed really well, like they had just come from a fancy dinner. She was in a short, tight black cocktail dress, and he wore a suit but no tie," the source said, adding: "It was only about 7:30 p.m., but they looked ready to be alone."

The insider also reportedly said that the two were escorted into the hotel by security and taken to a suite.

Earlier this month, reports surfaced that Affleck cut off contact with Ouzounian in an attempt to focus on reconciling with Garner. Following Affleck’s decision, Ouzounian has been planning on revealing secrets of her alleged relationship with Affleck and the "Gone Girl" actor's failed marriage in a tell-all book.

"Christine is very upset and says Ben should be worried. In her mind, this is far from over," another source earlier told OK! Magazine. "He’s [Affleck] afraid she'll use anything that he's ever told her against him," the insider reportedly said, adding: "Ben's even worried Christine may have recorded some of their conversations."

OK! Magazine's source said that Affleck is "really worried about Christine’s next plan of action," and that she could "become a real problem for him -- but he knows it’s all his own fault."
