Another source tells E! News,

"Someone at the table ordered it but staff was not explained what it was for." That is likely why Sofia's name was misspelled

"They are inseparable right now and not leaving each other's side."
"Scott is totally romancing her and she is under his spell. He took her away to Santa Barbara [last] weekend and is spoiling her with shopping trips and sweet gestures."
