Two months after kicking off promotion for his sixth studio album with reader-acclaimed hit single Fine China, R&B hitmaker Chris Brown returns with a follow-up sure to get listeners talking. On Don't Think They Know, beat duo Mel & Mus' swirling synth ambiance backs Breezy as he trades amorous, if secretive lines with a very unexpected guest: '90s hitmaker Aaliyah. Previously-unreleased vocals from the late, great R&B songstress are pulled from the vault to round out this sultry duet. The concurrently-released official visuals depict the headliner teaming up with a hologram of Ms. Haughton to broker peace between rival gangs. This record will be part of forthcoming full-length X, scheduled to drop July 16, via RCA Records.
