MANILA, Philippines - Sen. Bong Revilla and Cavite Rep. Lani Mercado renewed their vows yesterday afternoon at the Shrine of St. Therese of the Child Jesus in Villamor Airbase, Pasay City, to mark their silver wedding anniversary. They were first secretly married on May 28, 1986, at the Forest Lawn Memorial Park in Glendale, California. ‘It had to be secret because I was already four months pregnant,’ said Lani. They were married for the second time at the Imus Cathedral on March 25, 1998.
