What had ET readers buzzing this week?

1. First Photos of Giuliana & Bill's 'Miracle Baby'

On August 30, Giuliana & Bill Rancic welcomed son Edward Duke (via a surrogate) into the world and today they're giving everyone their first look at the baby boy!

Life & Style has the first photos and interview, where the new parents gush over the long-wanted addition to their family! "I had always heard that when you have a baby it completes your life — and it's true," Giuliana tells Life & Style. "I love my baby, and I love my new role."

"Every day he's changing — it's just remarkable to see," Bill adds. But Edward Duke isn't the only one changing! "It's amazing how maternal instincts have taken over, and Giuliana's just supermom," her hubby raves. "It literally brought tears to my eyes the other day watching her with Duke."

"I'd never changed more than a diaper or two in my life," Giuliana laughs. "Now it's like the littlest things that make me happy. I couldn’t believe that all those years of struggling and the tears actually paid off. Every shot, every doctor's visit — in the end, when you're holding your baby in your arms, you forget it all, and it's worth it -- [I'm] happier than I've ever been."

2. Julianne Hough: I'm 20 Pounds Heavier Since Dating Ryan Seacrest

Though there's no sign of love handles, Julianne Hough admits to InStyle Makeover magazine that she's packed on the pounds since first getting together with beau Ryan Seacrest.

"I'm 20 lbs. heavier than I was when we started dating," the 24-year-old cover girl confesses. "And now we always have great wine, and I can tell the difference. So I told him, 'You ruined my life because I can't go to a friend's house and drink cheap wine anymore.'"

Hough and Seacrest, 37, first met back in 2007, but the former Dancing with the Stars pro says she was initially apprehensive about dating the uber-successful American Idol host. "I was reluctant because he is such an influential guy, and what if it didn't work out? ... Our first date, I was so nervous that I just sat there and interviewed him with questions like, 'Are you loyal?' and 'Are you close to your family?'"

With Hough's movie career taking off and Seacrest adding NBC Olympic commentator to his already loaded work schedule, the couple must get their affections in where they can. "When we do see each other, we are super excited and do these cute and romantic things," Hough gushes.

For more with Hough, the InStyle Makeover hits newsstands Friday, September 14th.

3. Kirstie Alley Defends Tom Cruise & Scientology

The always candid Kirstie Alley opened up to ET about Scientology and the recent, controversial Vanity Fair article (that claims Tom Cruise "auditioned" women as potential mates with the help of the Church of Scientology), explaining why she felt she needed to defend her friend.

"I think whenever you have articles written that are third and fourth parties' opinions – it's like the game Gossip and you don't get the truth – I think that a magazine of that caliber should have interviewed him, and then they would get the truth," explained Kirstie, a noted Scientologist herself. (Vanity Fair writer Maureen Orth told ET that she tried to get an interview with Tom but was denied.)

Kirstie added, "I think that probably all religions sound bizarre to the people who are not the practitioners of them. … To me it's so normal, and probably 90% of the crazy stuff I hear isn't true."

Kirstie was in the Big Apple for the debut of friend and fashion designer Zang Toi's Spring 2013 collection for New York's Fashion Week. She also talked up her reunion with her pro partner Maks for the upcoming Dancing with the Stars: All-Stars…
