One day, two hot dresses! Jennifer Lopez turned up the heat in Miami, Flor., yesterday in a pair of wow-worthy looks while promoting her upcoming film The Boy Next Door (in theaters Jan. 23) that we can't stop talking about.

To appear on the morning show Despierta América, the triple threat glowed in a sexy David Koma halter-neck pencil dress that featured a net hem and major cutouts (above, right). Later that day at a VIP screening of the movie, the star rocked another design by David Koma—this time a sky blue crop top and paneled pencil skirt with a sheer hemline similar to that on the first outfit (above, left). Lopez paired both ensembles with a Harry Kotlar diamond ring, dazzling hoop earrings, and bejeweled ankle strap pumps, trading in her morning topknot for an afternoon blowout and keeping her face fresh. One question: How does J. Lo always manage to look so incredible?
