“We experienced that bit of pain -- well huge amount of grief -- so we developed compassion,” Alexandria tells Dr. Phil in an exclusive interview airing Thursday.

Alexandria says that she and her twin sister, Anastasia, were especially close. “We had a lot of friends. We were captain cheerleaders and ran track and cross country,” she says of growing up. “I just think that our relationship we had so much love for each other because of what we experienced together at such a tender age of five.”

She says their relationship remained tight even as they opened Twin Power Yoga Studio in Florida and became local celebrities.

“One of your clients said that you guys were highly visible, magnetic. You were trailblazers. You were really beloved,” Dr. Phil says. “And they say the media loved you guys because you were blonde, beautiful, successful, magnetic, drove matching Porsches. Just, were kind of the darlings, and that that was kind of charismatic for everybody.”

Over the years, Alexandria and Anastasia also became known for their legal troubles. They eventually moved to Hawaii, where on May 29, 2016, they plunged off a 200-foot cliff in a car after what witnesses described as a heated and violent argument. Alexandria was driving and Anastasia was killed.

On Thursday's episode of Dr. Phil, Alexandria speaks out for the first time since her twin sister’s tragic death, and since a judge ruled this was an accident, not murder. Check here to see where you can watch.
