Jessica Biel and Justin Timberlake are incredible parents, according to one of the actress' best pals!

Beverley Mitchell, who played Jessica’s sister on the hit WB show 7th Heaven for 11 seasons, opened up to Entertainment Tonight about her close relationship with the actress and new mom. “I would describe our friendship as a sisterhood for sure just because we’ve gone through the ups and downs,” Beverley said. The two women also attended each other’s weddings -- Jessica was a bridesmaid at Beverley’s 2008 nuptials.

Naturally, the 34-year-old has met Jessica and Justin’s newborn, Silas, and gushed to ET that he’s “adorable,” adding that the two are amazing parents.
“They are both so natural and they are both so excited and they are such an amazing couple and they are such an incredible team,” said Beverley, who is a mom herself, and recently welcomed her second child, Hutton. “This has been such a very natural move for both of them and I'm so thrilled that I am able to be there with them in this incredible experience of parenthood.”

So, do Justin and Jessica want more kids?

“I think as every parent of a newborn, you just go day by day,” Beverley explained. “You can’t really plan the future, I mean, you just gotta.. you’re just trying to get through the week!”

Beverley also said she loves going through mommy-hood with her gal pals, including sisters Haylie and Hilary Duff.

“It’s amazing that I’ve got this opportunity to go through this experience with my friends and that our kids are going to be able to grow up together and that we as mothers can just sit back and talk and chat and go through the ‘oh, today was a rough day’ or the highs of the day or the lows of the day,” she said. “I’m very grateful.”

Beverley, whose oldest child is 2-year-old Kenzie, has teamed up with RoseART to paint a football field-sized chalk paint mural at Santa Monica Pier in an effort to inspire kids to get outside and be creative. The mom of two also presented the Boys & Girls Club of America with a $50,000 check on behalf of RoseART to support summer art programs nationwide – and says Kenzie is loving the washable chalk herself.

“It’s incredible just to see Kenzie get so excited about things and seeing the enthusiasm for something… literally to see her just light up and just be like out of her mind excited to go in the front yard and just paint a little mural on the driveway… she was like shaking she just loved it so much!”

And Beverley promised Hutton and Silas will be joining Kenzie in the mural painting department as soon as they are ready. “Absolutely, when the day comes when they’re ready to go outside, they will definitely be playing with some chalk paint.”
