Jaime King on How Her Son James Makes Her a 'Better' Person

— -- Jaime King couldn't be happier.

The "Hart of Dixie" actress attended the Met Gala last week while pregnant with her second child and even though she admits she still felt the pain from wearing high heels days after the event, "it was my favorite Met thus far."

King, 36, went to the Gala with Jason Wu for Hugo Boss with a custom dress that was a showstopper. Wu is one of her closest friends, so she said the night felt like she went with family.

"It was emotional in a great way for me," she told ABC News about the Gala.

King added that she loves being pregnant.

"It doesn't matter if I don't sleep and have insomnia and feel like crap, all that physical stuff that goes along with it, cause at the same time, there's just like this human being inside of you, it's such a magical and sacred experience," she said.

King announced that she and her husband Kyle Newman were expecting again this past February. She has been open about how her and her husband tried for four years to get pregnant with their first child, James Knight, and how motherhood has been the actress's greatest gift.

"Looking at my son now, who's 18 months, and having another on the way, it makes it even more exciting, cause I know what it's like," she said. "It feels like there's so much magic in my life. I rediscover the world through seeing this little person. When you watch and see his sense of self discovery, his joy and happiness, it makes me a much better human being."

King said no matter how hard life gets, knowing that she only has years with her son until he grows up pulls her away from the stresses and "totally changes my point of view on how I live my life."

"I just feel really blessed," she said. "When I reflect on my life ... I just realize all of your hard work and all of your perseverance and you good values and what it is that you put out into the world, will come back to you. I didn't come from a lot, but I came from a lot of love."

With a second baby on the way, King revealed two months ago that dear friend Taylor Swift would be the newborn's godmother.

"The greatest gift about having her (Swift) in my life and having as the godmother to my upcoming child is just having her and everything that she encompasses," King said. "She's one of the most loving and compassionate, loyal people that I know. She is such an incredible light on this planet. The way she treats her fans and family just consistently stuns me with how beautiful she is."

King said what sums up how she feels about Swift is a speech she recently posted that the "1989" singer said while on her new tour.

King spoke to ABC News as part of a collaboration with Plenti, a loyalty program with the likes of Macy’s, Hulu and AT&T. American Express is the operator of the Plenti program, which launched this month.

"I'm practical, I'm from the Midwest, so I grew up with coupons and saving my own allowance, so I could buy something," she said. "That was how we had to live, we didn't grow up with a lot of money."

King said she is in favor of any rewards program, because as she is paying say an AT&T bill, she is earning rewards towards something practical like a tank of gas.
