First look: 'The Mentalist' wedding

For The Mentalist's Patrick Jane (Simon Baker), Teresa Lisbon (Robin Tunney) has gone from colleague to fiancée. The couple, in a photo exclusive to USA TODAY, tie the knot in an outdoor wedding in the CBS drama's two-hour series finale (Feb. 18, 8 p.m. ET/PT).

"It was sweet. It was vulnerable and touching," Baker says. "It was very personal, that moment where he turns in the field and sees her, just the two of them alone."

Tunney, accustomed to seven seasons of Lisbon's more practical on-the-job wardrobe, "felt uncomfortable wearing high heels and a dress. But it was beautiful," she says. "I feel the finale is a departure. It's like The Mentalist giving you their greatest version of a romantic comedy. I think it totally works."
