Nicole Richie and Christina Aguilera popped out a baby bella and beau (respectively) at Britney Spears ' former base Cedars-Sinai Medical Center on Saturday.

And even though there is no guarantee that the little babes will become buddies, at least they can bond over the fact that they both have yummy mommies who don’t mind the pregnancy pounds.

"At first I guess it was weird for Nicole to be gaining weight so fast after having been so small," a pal of the "Simple Life" star told Pop Tarts. "But she has finally learned to appreciate the importance of being healthy and she just glows. Being pregnant has done wonders for her figure."

So will Richie run rampant to pop those pregnancy pounds like so many Hollywood hotties seem to do these days?

"I don’t think she’s thought about [that] too much," said our source. "Nicole just wants to focus on being a mom. Perhaps she feels a little fat compared to how she was a year ago, but all her friends and family think she looks beautiful. I think Nicole quite likes those extra curves." (And for the record, Pop Tarts totally approves of Richie’s baby-bearing body!)

Lionel Richie's little granddaughter was named Harlow Winter Kate Madden and weighed in at 6 pounds and 7 ounces.

And in the very same ward, Max Liron Bratman was delivered by Aguilera. Judging by Christina's recent Marie Claire cover, where she bared her baby belly, the pop princess is proud of those pregnancy pounds, too.

Kevin Connolly’s No-Porn Policy; Minnillo Leaves Lachey for Keibler

When it comes to Sin City, not a night goes by that doesn't give Pop Tarts something to snitch about.

"Entourage" star Kevin Connolly popped by swanky spot JET at The Mirage to sneak a peek at Strip Las Vegas’ two-year anniversary party. (And also to check in with his pal, porn princess Jesse Jane, who hosted the bash). You may recall Jesse appeared (as herself) in an episode of his hit HBO series.

With the AVN Adult Movie Awards taking place over the weekend, the hotspot was filled with adult entertainers — but the media-savvy star made it his duty NOT to be snapped with any ladies in lingerie or less.

"Everytime somebody tried to take a picture of Kevin with one of the porn stars, he bolted," an insider told us. "The last thing he wanted was for rumors to start that he was canoodling with these women. And as far as we know, he was successful with his no-porn-picture policy."

Meanwhile, former MTV host Vanessa Minnillo and her hottie boyfriend Nick Lachey were busted down the road at party palace PURE getting down and dirty with pal Dave Navarro (who was celebrating his five AVN nominations for his directorial debut in the X-rated "Broken").

However, according to insiders, Ness left Nick alone to sip Grey Goose just after midnight when Stacy Keibler turned up.

"Vanessa and Stacy looked like long-lost sisters as they giggled and danced together all night," said our spy. "And with those two busting their moves, every guy was in his element."

But obviously Lachey recovered from his bella boogying with another, because the comely couple was caught getting cozy the following night at the luxe LAX at The Luxor.

Over at Opera in Hollywood, however, prying Pop Tarts popped Lindsay Lohan’s ex Wilmer Valderrama holding a reunion with the pals he partied with while hosting a New Year's Eve party at Palladium in Acapulco, Mexico.

We sighted no bell-bottoms on the "That '70s Show" sensation, but he did show a little "Night Fever" by insisting on a table right by the DJ and busting a few moves when Soulja Boy hit the speakers.

Tom’s 'Secret' Lunch With Schwarzenegger

Two of Tinseltown’s mightiest men (aka Tom Cruise and Gov. Arnold Schwarzenegger ) were caught chomping and chowing down lunch at Café Roma’s in Beverly Hills on Saturday.

But even though the pals were sitting in one of L.A.’s most touristy areas, it suddenly became a no-pic zone.

Eyewitnesses told Tarts that some pumped-up passersby apparently tried to take a happy snap of the pair, but were prohibited by Mr. Cruise at the pasta-lovin’ property.

"Both Tom and Arnold are regulars at the restaurant and the staff does look out for them," a nearby retailer said. "A few people wanted to take Tom’s picture, but he turned them down. A lot of sad faces came away from the scene."

Makes us wonder what they were whispering about…
