The 31-year-old model filed for divorce from the rapper last September after a year of marriage, but admitted in her post that she "prays, dreams and hopes" the two will get back together.
"My #ManCrushEveryday you know what it is.... We went wrong somewhere and even if we never ever get back together ( Even tho I pray, dream and hope we do) he will forever be the love of my life," she captioned a photo of the two sharing a kiss.
"The media doesn't make it easy but [expletive] them we gotta live for reality and not society," added Rose. "We forever have a bond because we made a beautiful baby from our Love. Through all the ups and downs of our relationship my heart still beats for him."
Rose and Wiz Khalifa tied the knot in July 2013 after two years of dating. The couple are parents to a 2-year-old boy named Sebastian.
Both Rose and Wiz Khalifa have spoken publicly about their opposite views regarding the demise of their marriage. The model claims things ended because Wiz Khalifa was unfaithful, but the rapper has vehemently denied any wrongdoing.
