The song "My Heart Skips a Beat" was originally written and performed by Buck Owens in 1964. It became a number one hit on the U.S. country singles chart.

Another popular song titled "Heart Skips a Beat" was released by English singer Olly Murs featuring Rizzle Kicks in 2011. This version is a pop/hip hop song and different from Buck Owens' country classic.

To clarify:

• If you mean the classic country song "My Heart Skips a Beat," it is by Buck Owens.
• If you mean the pop/hip hop song "Heart Skips a Beat," it is by Olly Murs featuring Rizzle Kicks.

Both are well-known songs but in different genres and eras.
