"The Best Thing About Me Is You/ Lo Mejor de Mi Vida Eres Tú" is a song by the Puerto Rican recording artist Ricky Martin, taken from his ninth studio album Música + Alma + Sexo. It was released as the lead single from the album to iTunes on November 2, 2010. The song had earlier premiered on radio's Ryan Seacrest show. The original English version of the song features singer Joss Stone, while its Spanish version, "Lo Mejor de Mi Vida Eres Tú", replaces Stone's vocals with Natalia Jiménez. Ricky Martin recorded also a Banda Remix of "Lo Mejor de Mi Vida Eres Tú" featuring Jenni Rivera. In Germany and Austria, "The Best Thing About Me Is You" featuring Edita was released. Martin performed this song with Stone for the first time on The Oprah Winfrey Show on November 2, 2010.
In 2011, "The Best Thing About Me Is You" was included on Martin's 17: Greatest Hits album, released in the United Kingdom.
In a Billboard interview, Martin describes the track: "I told Desmond -- and I'm not making comparisons -- but "Don't Worry, Be Happy" is great. That's how this song came to be. From being in a very cool place in my life."
Carlos Quintana from About.com, positively reviewed the track, saying: "this song is probably the most reflective, inspiring and positive of the whole album." Ernesto Lechner from the Los Angeles Times said that "the lyrics of "The Best Thing About Me Is You," a duet with Joss Stone, sound a bit forced in English, the Spanish version of the tune crackles with bonhomie." Joey Guerra from Houston Chronicle praised the Spanish version, saying: "he lightens up a bit on "Lo Mejor de Mi Vida Eres Tú", that boasts an easy chemistry," but criticized the English-language version, calling it: "less successful" because of "Joss Stone’s habitual oversinging." Grace Bastidas from Latina said: "The first single from the album, "Lo Mejor de Mi Vida Eres Tú" features Spanish siren Natalia Jimenez—Joss Stone duets in the English-language track—and is the definition of happiness. There’s even some laughing and giggling at the end of the song in case you’re not already smiling." Leila Cobo from Billboard said that the song is "a feel-good ditty over a happy reggae beat."
The music video was filmed on 20 and 21 December 2010 in Miami and directed by Carlos Pérez. The video for the English version premiered on Ricky Martin's VevoYouTube Channel on January 11, 2011 and got two million views in two days. Joss Stone does not appear in the video. The Spanish version of the video was released on Univision and also does not feature Natalia Jiménez.
