Lindsay Lohan (العَرَبِيَّة)
After that whole accent fiasco, Lindsay said that her new way of speaking was caused by her language studies. She claims to be fluent in French, understands Russian, and is learning Turkish, Italian, and Arabic. It's unclear if she's currently keeping up with her Arabic studies, but we will never forget the time she confused the word 'beautiful' for 'donkey' in an Arabic-appreciation Instagram post.
Ariana Grande (日本語)
Ari seems to be more of a dabbler when it comes to languages. Especially Japanese. She has studied the reading and writing of hiragana, as well as spoken some basic sentences or phrases in Japanese, but her conversational (as well as katakana-reading/writing and/or kanji) level is unknown — though, it's safe to assume she is still かたこと (katakoto), since she's been delving into it from time to time for years.
Selena Gomez (Español)
Being half-Mexican herself on her father's side, Selena has admitted to experiencing trepidation at Latin award shows and interviews because she doesn't speak Spanish. She explained in a 2010 interview with Latin.com that she can pick it up well through her listening skills, but her conversational level is as low as her confidence is in speaking it. She has gone back and forth in believing that she needs to speak the language in order to be accepted as a "real" Latina, which is seemingly true with some people, while others are more encouraging. Either way, Selena appears to lack a shield for the bad comments that get thrown her way, and the so-called "outrage" over her poor pronunciation in her Spanish-speaking commercials and songs seems to have discouraged her as of late.
Ashley Olsen (Française)
Ashley revealed in 2006 on Much On Demand that she's been studying French "for so long", from high school to college, and that she would love to be fluent in it. She even expressed interest in moving to France and living there for a while to really immerse herself in the language. However, she has never been seen speaking it publicly and it seems she has given up on it a long time ago. What is relevant in that same interview though, is Mary-Kate scoffing it off, saying, "we studied it in high school and just... never got passed the [beginner level]."
