Actors David Duchovny and Tea Leoni have sparked reports of a reconciliation less than a month after separating.

The couple announced its split in October after 11 years of marriage - just one week after Duchovny checked out of a rehab clinic in Arizona following completion of treatment for sex addiction. The pair had been separated "for several months", but opted to keep the news private for the sake of their two kids, Madelaine, nine, and Kyd, six, according to a statement from their representatives.

However, reports of a reconciliation ignited when they were reportedly seen celebrating Halloween together on New York's Upper East Side on Friday night. A source tells the New York Post the pair "looked very mellow and relaxed", as they took their kids trick-or-treating. The source adds, "They were very cute and were holding hands."

Duchovny and Leoni wed in May, 1997 after a whirlwind romance.
