Things may be looking up for New Jersey Sen. Bob Menendez, who confessed last year, “My love life stinks.” The divorced pol, 57, considered one of the most powerful Democrats in the country, was spotted on a date last week at Charlie Palmer’s Steakhouse in DC with Celia Brown — a salesclerk in the Capitol Hill gift shop. Our spy described his lovely lady as “late 30s, dark hair and big lips.” Sounding already well media trained, she told us by phone, “I’m not going to com ment on my personal life.” His spokesperson said, “Not now or at any time has Sen. Menendez talked about his private life.”
