Lil Wayne Shades Christina Milian Baby Heartbreak, Supports Chris Brown Tour Amid Rihanna Diss

Christina Milian's baby nephew suffered a life-threatening condition and tragically died just hours after birth on August 27, 2015:

The last 24 hours have been an emotional roller coaster but i'd like to thank everyone for being so supportive throughout my sister Danielle & Richards pregnancy. The both of them have shown the true measure of courage and faith for the last 9 months and I can't praise them more. Our family was blessed to have met our little Angel Baby Richie. We were fighting for him and with him the whole way and are now coping with the direction in which fate took. I ask that you keep him and our entire family in your prayers -- Especially Danielle, Richard, Naomi & Dj and know that we've all been touched by our little Guardian Angel. His memory will forever live on in our thoughts and our hearts. May he now rest in peace in the arms of our Heavenly Father. <3 stay blessed.

The R&B sweetheart's close-knit family continues mourning the lose of little Richie. Earlier this week, several friends and loved ones gathered on the beach to honor the child's short-lived (but always cherished) memory:

And still, Milian's rumored boyfriend Lil Wayne was nowhere in sight to provide his love and support. Instead, the YMCMB rapper was in Miami performing with Chris Brown and French Montana:  

Instead of hyping Breezy's One Hell of a Nite tour, should Weezy have flown back to Malibu in order to support his girlfriend during such a difficult time?

Once upon a time. Forever Loved & Always Remembered. We love you Richie Bear. r.i.p. A photo posted by Christina Milian (@christinamilian) on Sep 2, 2015 at 11:24pm PDT

The "Rebel" songstress remains fully dedicated to her "Glory" beau, but should she demand more respect and attention?

Meanwhile, 26-year-old Brown also continues having issues with his on-and-off again hip-hop lover, Rihanna...
