Lindsay Lohan will be allowed to receive gifts during her rehab stint at the UCLA facility. However it has been revealed that certain objects may be deemed unsafe for the troubled actress.

TMZ are reporting that patients in Lohan's building are not allowed to receive certain items from the gift shop that may be deemed unsafe ... items like "balloons, breakables, and anything with sharp points."

Employees at the rehab facility recommend “soft, cuddly things." Fans are being advised not to attempt to shower the Mean Girls star with gifts as she will not receive them. We're told, "Lots of people are calling in trying to get [Lohan] gifts ... but all of her information is restricted ... so anything you try to buy will not get to her."

Lohan entered rehab on Monday after being released from the Century Regional Detention Facility. She served 14 days of a 90 day sentence.
