In June 2013, Aaliyah was featured on a new track by Chris Brown, titled "Don't Think They Know"; with Aaliyah singing the song's hook. The video features dancing holographic versions of Aaliyah. The song appears on Brown's sixth studio album, "X". Timbaland voiced his disapproval for "Enough Said" and "Don't Think They Know" in July 2013. He exclaimed, "Aaliyah music only work with its soulmate, which is me". Soon after, Timbaland apologized to Chris Brown over his remarks, which he explained were made due to Aaliyah and her death being a "very sensitive subject".
