Fifty-eight days after giving birth, Teen Mom 2 star Kailyn Lowry has officially given her third child a name.
Lux Russell is the official name Lowry chose for her newborn son.
Taking to Instagram the star captioned, 'It only took us 7 weeks to decide a name and 8 weeks to make it official.'
When a commenter inquired why it took so long for the MTV star to decide on a moniker, she replied: 'Well, for one, I didn’t know if I was having a boy or girl. And for two, maybe I wanted to see his/her first before deciding.'
Up until yesterday, Lowry had been calling her new addition 'Baby Lo,' a nod to his dad, Chris Lopez.
The 25-year-old is also mom of Issac, 7, with former boyfriend Jo Rivera and Lincoln, 3, with ex-husband Javi Marroquin.
