KELLY BLOWS UP!

Stress-eating is taking a heavy toll - INSIDERS

STRESSED songbird Kelly Clarkson is dealing with the pressure from her bitter divorce battle with estranged hubby Brandon Blackstock by pigging out and piling on the pounds, sources dished.

The expanding daytime darling claimed she’d dropped an impressive 37 pounds last summer. But tipsters told The National ENQUIRER the “Since U Been Gone” singer, 38, has gained it all back — and then some!

“She’s stuffing her face to fight off the anxiety from the divorce, but all that late-night comfort food and wine has left her looking like a linebacker!” an insider spilled.

As The ENQUIRER previously reported, the talk show host filed for divorce from Brandon, 44, in June after seven years of marriage. She was granted primary custody of their kids — daughter River, 6, and son Remington, 4.
