Jennifer Garner's representative rubbished rumors that the actress and husband Ben Affleck are expecting their fourth child.

Earlier this week, Star magazine reported that a family insider had told them that actress Jennifer Garner was expecting her fourth child and that the pregnancy had come as a shocker to her and husband Ben Affleck.  The report also suggested that the pregnancy will also help revive the couple's marriage, which is currently on shaky grounds due to Affleck's gambling problem, according to Radar Online.

"Ben has been going above and beyond lately: He's checking up on Jen all the time and surprising her with flowers," a source told the tabloid. "Jen thinks this baby could be the key to making her marriage strong again."

Speculation has swirled suggesting the Dallas Buyers Club star is pregnant yet again after she was photographed on two separate occasions in July, showing off what appeared to be a baby bump.

However, the actress' representative Meredith O'Sullivan has squashed the rumors, telling TMZ that Garner is not with child.

The mother of three had publicly admitted that her husband, Ben Affleck, has "wonder sperm." But, she's also been very vocal saying she's done.

She told The Ellen DeGeneres Show in November of last year, "There are 57 kinds of contraceptives used pretty much [every day]. Three of them are under the age of 8. But yes, so far so good, ha. Stop it, stop it in its tracks. I think we have provided the world with enough."

The couple tied the knot in 2005 and they share three children together - eight-year-old Violet, five-year-old Seraphina and Samuel, who was born in 2012. Eight months after giving birth to Samuel, the actress travelled extensively with Affleck to promote his movie "Argo."

"He said, 'I need you to come with me.' So my breast pump and I travelled all over the world with him," the actress told Hello! Magazine during a previous interview. "It's a question of priorities - Ben is mine as I am his."
