Lala has multiple roots: in Persian/Hindi lala means "tulip" (also a Hindu honorific meaning "beloved"); in modern English it carries musical-association as a singsong syllable. La La Land (2016) — Damien Chazelle's romantic musical with Emma Stone and Ryan Gosling; won six Academy Awards including Best Director, Best Actress (Stone), and Best Original Song for "City of Stars" — tied the record for most Oscar nominations (14) with All About Eve (1950) and Titanic (1997); famously had Best Picture mistakenly announced before Moonlight won; grossed $447 million worldwide. Lala Kent — Vanderpump Rules personality. Lala Tribbiani — Friends episode character.
Lala does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Lala reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
