Jessica Simpson, dressed in a long, white dress (hey, isn't Ashlee the one getting married?) started her mother's day celebration early, with dinner at Studio City eatery Mexicali Saturday night.

Jessica's apparently such a regular at the Mexican restaurant that we hear they've even named a margarita after her!

But of course Jessica also made time for her mom on her special day - it's Tina who picked Jess up from the restaurant after dinner!

Happy mother's day!
