Jennifer Lopez  made a low-key departure from dance rehearsals in London Friday night. The American Idol judge is on a break from the show this Summer before auditions begin again in the Fall, and she's taking advantage of the extra time to focus her energy back on music, family, her new reality show Q'Viva the Chosen, and philanthropy. J Lo and Marc Anthony  stepped out in black-tie attire for the Hope For Children Gala in NYC  last week before Jennifer and their twins, Max and Emme , continued east to London. Marc is also busy promoting the new season of TNT's Hawthorne, and he'll be singing the national anthem at Sunday's NBA finals in Miami. While he's on center court in the states she'll be rocking hits from her new album LOVE? alongside Enrique Iglesias, Nicole Scherzinger, and Cee Lo Green and more from the UK.
