She definitely has a glow about her!

Possibly pregnant Jennifer Garner was all smiles as she chatted on the phone on Tuesday afternoon. Looks like Band-Aid baby No. 4 is on the way!

The mom of three showed off a clear baby bump while doing a little retail therapy near her home in Brentwood, Calif. Last week pregnancy rumors flew when Ben Affleck's bride was spotted with an unmistakable growing belly. And now it seems impossible to deny what our eyes are telling us!

Given the way the fabric clings to her stomach -- she's definitely not trying to hide her curves. We expect a pregnancy announcement any day now!

While Jen and Ben have stayed mum on the baby issue, Star confirmed that the Alias star has a bun in the oven.

Despite recent reports of some major marital woes, including gambling and cheating allegations, it seems as though the twosome are committed to making it work.
