Grey’s Anatomy star Ellen Pompeo is still glowing over the happy news of her pregnancy. And her music producer husband Chris Ivery has been by her side the whole time all smiles.

The parents-to-be left their home in Los Angeles this morning (September 9) looking happy as can be despite the rumours of his unfaithfulness.

According to Star magazine, Chris engaged in sexual relations with a “sexy 19-year-old blonde” restaurant host around the same time the couple announced their pregnancy.

“Yes, I had sexual relations with Chris,” says Rachel Artz. “We were intimate several times.”

Adds an insider: “Chris often took calls from Ellen in front of Rachel and talked about their baby-to-be.” Otherwise, the source adds, “He didn’t seem to like Ellen much when he talked about her. He made her seem like a diva.”
