Kate and Colin chatting?

Hollywood, CA (BANG) - The Hollywood hellraiser and the supermodel mom are believed to have bonded over their stints in rehab - but are to busy to hook up so have to whisper sweet nothings into their mobiles to each other instead. An insider is quoted on the National Ledger Web site, saying, "Since they're both working on their sobriety, they completely understand the struggle...Plus, they both happen to be very attracted to one another." Last year, Moss got help after being snapped snorting cocaine, while 'Alexander' star Farrell took time out for treatment citing 'exhaustion.' The pair have known each other for some time. [AHN]
