Gwen To Blake: Get Fit Or Get Out!

She Bans Booze & Burgers – So He'll See Their

- 

SLINKY pop princess Gwen Stefani has hit bloated beau Blake Shelton with a tough love ultimatum — “Shape up or ship out!”

“Gwen adores Blake — but she’s demanded he hit the gym or hit the highway!” an insider snitched.

It’s just the latest speed bump in the battling lovebirds’ rocky three-year romance — and came after the couple seemed to find new happiness when, as The National ENQUIRER reported, Blake had committed to sharing a baby with Gwen.

“They’ve had their conflicts, and Blake pledged to support Gwen — whether the child comes by adoption or IVF treatments,” the source spilled.
