“If You Really Love Me (How Will I Know)” is a 2021 single by David Guetta teaming up with MistaJam and singer John Newman to release a dance track based on an interpolation of Whitney Houston’s “How Will I Know”. The song became a hit in the UK, after charting a No.66 in the Top 75 (for the week ending August 5, 2021) after amassing a sales total of 7,018 units. The song became the fourth entry on that week’s chart for Guetta (though the only single out of the four chart hits where he took lead artist credit) and the first chart credit for Newman since “Give Me Your Love” with Sigala and Nile Rodgers in 2016.
