Guess Kim Kardashian wanted to deliver her "sweet prayers" to pal Lindsay Lohan in person.
Kardashian -- who Tweeted that fans should "send LL your sweet prayers" -- was seen visiting Lohan's L.A. home on Wednesday night, as RadarOnline captured on video.
After being sentenced to 90 days in jail and 90 days in rehab on Tuesday, Lohan apparently opted to stay in -- bailing on a belated birthday bash in her honor Wednesday at L.A. club Las Palmas.
A Lohan source at Las Palmas told UsMagazine.com that Lohan is "not handling this well at all. She's at her lowest."
Another pal at the Las Palmas party added that Lohan is "beside herself. She's with her mom, sister, assistant. She couldn't bring herself to leave the house...she finally felt bottom."
And although the Mean Girls star likely won't serve anywhere near 90 days in jail, the source says even "one day is too much. That girl cannot handle jail. She is scared out of her mind." (Back in 2007, the actress spent 84 minutes behind bars.) See more about the power of good friends.
But the source was optimistic for the star, too. "It's like a switch went off today. She's just carefully plotting how to stay above water."
Lohan is to surrender to authorities July 20.
