Just hours after Billy Ray Cyrus filed for divorce ... his soon-to-be ex-wife Tish was out in Los Angeles, getting some serious emotional support from her two kids.
While Miley was MIA, her younger siblings Braison and Noah spent some quality time with their mom ... whose eyes were hidden behind dark sunglasses. Tish's forearm tattoo -- which reads "She wants to fly" -- was in plain sight, however.
As we previously reported, Billy Ray blamed the split on irreconcilable differences. The couple has been married for 17 years.
