Universal Pictures has revealed the trailer from writer/director Nancy Meyers' upcoming romantic comedy, It's Complicated, starring Meryl Streep, Alec Baldwin, Steve Martin, John Krasinski, Zoe Kazan, Lake Bell, Hunter Parrish, Pat Finn and Rita Wilson.

Opening in theaters on Christmas Day, the film centers on Jane (Streep), who is the mother of three grown kids, and owns a thriving Santa Barbara bakery/restaurant and has-after a decade of divorce-an amicable relationship with her ex-husband, attorney Jake (Baldwin). But when Jane and Jake find themselves out of town for their son's college graduation, things start to get complicated. An innocent meal together turns into the unimaginable-an affair. With Jake remarried to the much younger Agness (Lake Bell), Jane is now, of all things, the other woman.

Caught in the middle of their renewed romance is Adam (Martin), an architect hired to remodel Jane's kitchen. Healing from a divorce of his own, Adam starts to fall for Jane, but soon realizes he's become part of a love triangle.

Should Jane and Jake move on with their lives, or is love truly lovelier the second time around? It's... complicated.
