Pregnant Rachel Bilson Hides Her Baby Bump During Red Carpet Appearance

Rachel Bilson was pregnant during her red carpet appearance at the CW Upfronts

Unbeknownst to the rest of the world, Rachel Bilson was pregnant during her red carpet appearance at the CW Upfronts last week in New York City. 

The 32-year-old mama-to-be looked every bit the fashionista in a Mary Katrantzou floral dress which perfectly hid her bun in the oven. 

The Hart of Dixie star paired the look with Bionda Castana white pumps with black ankle straps. 

Bilson chatted with E!'s own Kristin Dos Santos during the event and gushed about working on the upcoming season of her hit show. 

"I guess I felt pretty good because we have a solid thing going at this point and we have so many fun things to play with and it's so different from any other show on the network," she explained. 

"I'm lucky with all my co-stars and also Zoe is an idiot and it's fun playing an idiot." 

Bilson also joked that she felt like she was one of the older stars on the CW roster this season, saying, "I'm like an old timer here with all these youngins' and their new shows and I'm old mammy." Hardly! 

Earlier today E! News confirmed that the adorable brunette is expecting her first child with longtime beau Hayden Christensen. 

The good-looking duo began dating in 2007 after meeting on the set of the action-packed film Jumper. 

The co-stars got engaged in December 2008 but called it off in August 2010, only to reconcile three months later.

Mila Kunis and Ashton Kutcher's Louisiana Menu: Tacos, Beer and Ice Cream!

Ashton Kutcher & Mila Kunis: The engaged couple were spotted enjoying a trip to the South recently

Ashton Kutcher and Mila Kunis' trip to Louisiana seemed more like a vacation for their taste buds than anything else! The engaged couple were spotted enjoying a trip to the South recently, taking full advantage of the delicious southern food and E! News has the exclusive details. 

We learned that the soon-to-be parents made two yummy stops on Tuesday, with one of them being at the Tacos & Beer restaurant in Old Town. "They were here for about an hour," the restaurant owner said of the actor and pregnant beauty, adding that, "Ashton had a big burrito and a beer while Mila had the carne asada dish with tea and water." 

The manager also noted that the stars took pictures with fans at the restaurant and said, "They were really cool, and very nice. They were just having a good time." 

Along with some tasty Mexican food, the pair also satisfied their sweet tooth by grabbing some ice cream. Mila and Ashton stopped by the Slidell Soda Shop in the same part of town, where they stayed for about 20 minutes. 

"Mila was trying out all kinds of ice creams. She tried the Rocky Road and then got two scoops of Thin Mint," a source exclusively tells E! News, and mentioned the Soda Shop has the best ice cream in town. "Hopefully if she gets more ice cream cravings so they will come back."
