Better late than never.

Lindsay Lohan's birthday was July 2, but the "Mean Girls" star was in rehab on that day as part of a 90-day, court-mandated stay.

So, the Lohan family decided to wait till she got out to celebrate. Lohan, who turned 27 last month, posted a collage of pics on Instagram, including those of her grandma and her mom, Dina Lohan, a "Happy Birthday Lindsay" cake and one of her smiling from ear to ear.

Along with the pics, Lohan wrote, "Belated Birthday to me with @nanasullivan & @dinalohan #lohanhouse :)"

Everyone is dressed down and casual, which goes with Lohan's attempt to turn over a new leaf post rehab.

Out only two weeks, Lohan's landed a role on "Eastbound & Down," hosted an episode of "Chelsea Lately," tweeted at the White House and sat down with Oprah.
