Joe Odom couldn't contain his happiness as he stepped out to do some shopping, close by the hospital where Lamar remains.
Wearing a cap and suit jacket, Joe appeared in good spirits, after speaking out just days ago to beg Khloe Kardashian to update him on his son's progress.
Lamar is reportedly breathing on his own after showing a huge improvement following his terrifying collapse.
The 35-year-old former basketball star is said to have regained consciousness on Friday after being found unconscious in a Nevada brothel earlier this week and TMZ reports that he is now "breathing completely on his own".
He is still using an oxygen mask but a source told the website: "This is the best 24 hours he has had so far."
It has also been reported that Lamar has been able to respond to doctors physically and verbally.
