Taking a queue from Tom Hanks in Castaway, Spencer has been growing out his blonde beard for months.

“Shaving. Lost my razor, but this should work,” he just Tweeted.

Spencer’s wife Heidi Montag recently filed for divorce, but RadarOnline.com reported exclusively that the on again, off again couple has been secretly living together and seems like the two are back on after they were caught kissing, holding hands and hugging at the zoo on Heidi's 24th Birthday.
