Liza Morales took to Twitter on Tuesday for the most tragic of reasons.
Lamar Odom's ex-girlfriend wrote a special social media message in honor of Jayden, the son she had with Lamar who would have turned 10 years old yesterday.
"Happy 10th Birthday to our Guardian Angel, our beloved son, Jayden," Morales penned alongside a graphic of colorful balloons floating in the air.
She added the hashtag "#BirthdayInHeaven" to her post.
Odom and Morales were in a romantic relationship for over a decade.
They currently share two kids, Destiny and Lamar Jr., as Jayden, passed away in 2006 at just six months old as a result of SIDS (sudden infant death syndrome).
It's just one of many tragedies Odom has endured throughout his life, as noted below:
In October, Morales and the children flew out to Las Vegas to be with Odom after he fell unconscious and was placed in critical condition.
She has feuded with Khloe Kardashian at times over the years, most recently taking shots at Khloe for abandoning her family when thinks got difficult.
There was also talk that Morales and Kardashian clashed a couple months ago over Odom's life insurance policy.
But all that matters at the moment is the unspeakable pain Morales must be in, having lost a child.
"I had to depend on my spirituality . . . Lamar turned to work," Morales said in 2012 of how each handled the tragy.
"He had his music he was working on, a clothing company and an artist he was working with - that's how he dealt. I was alone during that time, but at least I had my family and friends.
"The loss never leaves you, but it does get better. We have pictures of Jayden around the house and the kids and I talk about him all the time.
"We are in a place of peace and acceptance."
