Pao and Russ are one of the couples returning for "90 Day Fiance: Happily Ever After?" Season 2. The two were first introduced in the first season of the reality show. Russ is an Oklahoma resident, while Pao is an aspiring model from Colombia.

Pao goes to Miami

In the new "90 Day Fiance: Happily Ever After?" season, fans will see that Pao and Russ are still married, but are living separate lives. Pao has left Russ in Oklahoma to pursue a modeling career in Miami, Florida. She says she has always felt uneasy and uncomfortable living in Russ's hometown with his conservative family nearby.

In Miami, Pao seems to be enjoying her "single" life. She goes out partying with her Latina friends at night. During the day, she goes to various auditions and photoshoots in the hopes of becoming a full-fledged model. However, some of her shoots are over-the-top sexy, which when Russ wasn't happy about when he found out.

Meanwhile, Russ, a former engineer, is now jobless and technically, wife-less. He's devastated that Pao has deserted him, and he plans to sell his house so he can quickly follow her to Miami.

Pao goes blonde

But Pao's modeling career is not going as well as she thought it would.

Now the sole breadwinner in their relationship, she's determined to do everything to prove to Russ that she made the right decision. She consults with her agent, who tells her she needs to have a makeover to stand out.

Pao concedes and goes to the salon straight away. She colors her long, dark hair blonde--which makes her look like a totally different person!

She says in the confessional that she loves her new look, but we're not so sure. After all, she decides to keep this little information to herself and does not tell Russ about her drastic makeover. Will he even recognize her once he arrives?

"This is a new me. This is a new Pao," she says upon seeing her blonde locks.

In the show's promotional materials, Pao is already sporting her new blonde hair, and now fans will see the reason behind it.

Pao and Russ are still very much together, based on the photos the two have been posting on social media. Currently, they are in New York to promote "90 Day Fiance."
