Tristan Thompson has taken a big step to make sure that his 17-year-old brother Amari Thompson is safe after their mother, Andrea, died too soon.

TMZ says that the NBA player, who is 32 years old, has asked the courts to make it official that he is Amari’s guardian.

Amari has to deal with unique problems because he has a number of medical conditions, such as epilepsy, that keep him from taking care of himself.

Amari will get a fortune of $103,475 when their mother Andrea dies. This will help him have a better future.

Since their father, Trevor, isn’t around, Tristan Thompson is the only family member who can care for and support Amari during this hard time.

Andrea, their mother, died suddenly of a heart attack at the age of 53 in early January.

Khloe Kardashian shows support for Tristan Thompson after a change in his parenting situation.

In Los Angeles, Tristan Thompson and Amari went to stay with none other than Khloe Kardashian.

The choice was made because of a strange turn of events: bad weather caused a lot of damage to Tristan’s home, which was being remodeled at the time.

Khloe said on the season finale of “The Kardashians”: ” Tristan has a house he’s doing construction on, and he’s been renovating.

He was able to live there during renovations, but we had crazy weather for California, like extreme rain, and Tristan’s roof caved in on his home and caused flooding.

So Tristan and Amari are staying at my house right now, until his home gets fixed.”
