Britney Spears and Mel Gibson, who shared some quality vacation time in Costa Rica in May, further cemented their perfect union last night at a Los Angeles cigar bar, according to People magazine.

The odd couple were spotted at the members-only Havana Club, engaging in a two-and-a-half-hour rap session. “Britney looked like a doll with bright red lipstick,” noted a witness. “She looked pretty in new capri jeans [purchased earlier in the day at the Lisa Kline boutique in Beverly Hills, where she also tried on several necklaces], a blue blouse, white shoes and a brown bag.”

The onlooker added that the sometime singer was “very quiet” and bore a “serious look on her face as she walked into the Havana Club” shortly before 7 p.m. Well, sure, who wouldn’t look solemn as they prepared for a marathon session of the Gospel According to Mel?

The Lethal Weapon star, by contrast, bounded out of his silver Lexus and flashed a roguish grin as he entered the club clutching a “man-purse,” presumably filled with leftover Passion of the Christ nails.

Shame on these two. Haven’t they heard that smoking can kill a person?

Of course, in some cases, it doesn’t kill nearly quick enough.
