Usmagazine.com quoted Garber as saying, "Yes, she is," when asked if Garner and her husband, actor Ben Affleck, are expecting a sibling for their 2-year-old daughter, Violet.
Usmagazine.com quoted another source as saying, "(Garner) is five months pregnant. They are very happy."
Rumors about Garner's alleged second pregnancy have been swirling for weeks, mainly due to Garner's and Affleck's recent comments about wanting to expand their family. Adding fuel to the speculation is the fact Garner has been photographed wearing loose-fitting clothes this summer.
Garber told E! News that Usmagazine.com took his words out of context.
"I haven't confirmed that at all, no," Garber told E! News. "I know they want to have another child and hopefully that's true, but I don't know that. ... No, I know that they are hoping to be. I just don't know that it's for sure. It's a very... personal thing."
