Hey, after dating for only ‘3 months’ before getting engaged, you shouldn’t be surprised!

Grey’s Anatomy stars and engagement ring exhibitionists Kate Walsh and Katherine Heigl show off their blingin’ diamond rings at the premiere of parenthood comedy Knocked Up at the Mann’s Village Theater on Monday in Los Angeles.

Heigl on Walsh’s engagement: “She’s thrilled and I’m thrilled for her. She’s just one of the coolest chicks and deserves every joy and happiness. Can’t wait to see her ring!”

Heigl stars as an entertainment journalist who finds herself in the family way after a one-night stand with a goofball named Ben in the comedy Knocked Up, which opens next Friday, June 1.

The jet-setting Spider-man 3 cast takes on Madrid, Spain at Hotel Santo Mauro on Wednesday. Co-stars Kirsten Dunst and James Franco attend the photocall.

Dunst on Spider-Man 4: “I would only do it with Sam (Raimi) and Tobey (Maguire). You can’t do that to the fans one. You can’t do that to each other; we’re a team and we’ve grown up together now and what makes this movie special is our collaboration together on it. I wouldn’t do it without Sam or Tobey. We never felt like it was really an end anyway. I do feel like we ended a chapter with this film. I think this book is closed and now we’ll approach it in another way that will refresh all of us.”

Spider-man 3 opens in theaters nationwide on May 4.
