*Omarion went on a Twitter rant Monday after finding out that his single, “Post to Be,” was ignored by the Grammys this year.

Shortly after the 2016 Grammy nominees were announced this morning (Dec. 7), the singer and “Love & Hip Hop: Hollywood” star hit up Twitter to unleash his frustration.

The 31-year-old released “Post to Be” — a bouncy R&B number co-written by Chris Brown and Jhene Aiko — in November 2014 as part of his fourth studio album, “Sex Playlist.” Omarion thought he deserved a nod in the category of Best R&B Performance.

“The odds have always been against me. I constantly prove you wrong. I’ll consistently do great things & you will have to celebrate me,” read one of his Tweets.

After getting all of that out of his system, Omarion congratulated the nominees in the category. The singles nominated for Best R&B Performance included Tamar Braxton’s “If I Don’t Have You,” Andra Day’s “Rise Up,” Hiatus Kaiyote’s “Breathing Underwater,” Jeremih’s “Planes” featuring J. Cole, and The Weeknd’s “Earned It” from the Fifty Shades Of Grey soundtrack.
