Bristol Palin 's 15-year-old son Tripp Easton Johnston spent quality time bonding with his stepmother Sunny Oglesby Johnston on Sunday - two months after texting her that he was moving to Alaska in order to be closer to his father Levi Johnston.

'He just texted me,' the Texan-based 34-year-old recalled on Cheryl Burke's podcast on August 25.

'He's like, "Hey Mom. I'm not coming back." Oh, I couldn't even believe it! At first I'm like, "I'm coming up to Alaska, we're not doing this!" I was so mad. So mad.'

Bristol 'selfishly' wanted her 'best friend' to stay, but ultimately respected 'that he thinks this is what's best and he needs that relationship with his dad.'

'So as hard as it is for me, and it's so hard for my girls too, I know that he needs to grow that relationship with his dad,' Palin noted.

'And he loves Alaska so much, he's hunting and fishing all the time. So I know that it's going to be a good thing.'

The nepo-baby of former Governor Sarah Palin - who dreams of owning a second home in Alaska - visits Tripp 'every other month' and speaks with him via FaceTime 'every day before and after school.'

The aspiring motocross rider is also building a strong relationship with his three homeschooled half-sisters - Breeze Beretta, 12; Indy Rae, 9; and Delta Jo, 5.

This Monday will mark Sunny and 34-year-old Levi's 12th wedding anniversary.

Bristol and Medal of Honor-winning Marine Dakota Meyer share 50/50 custody of their two daughters - Sailor Grace Meyer, 8; and Atlee Bay Meyer, 7 - they welcomed during their 19-month marriage, which ended in 2018.

Palin was only 18 when she and her high school sweetheart-turned-fiancé welcomed Tripp, and the pregnancy was announced at the 2008 Republican National Convention and caused a mini-scandal in the vice presidential campaign of her 60-year-old mother.

After their five-year relationship ended in 2010, the Boy Hart founder competed on two season of ABC dance competition, Dancing with the Stars, in 2010 (placing third) and 2012 (placing ninth).

Meanwhile, little Tripp and his dance partner Hailey Bills were the first pair eliminated in ABC spin-off Dancing with the Stars: Juniors in 2018.

On June 19, Bristol revealed her branch of the real estate company Austin Home Seekers 'closed well over $100M in overall sales volume within the last six years.'
