Washington (CNN) – Her birthday may be Monday, but some of the biggest gifts Ann Romney brings in will come the day after.
Mrs. Romney is the guest of honor at a birthday fundraising event Tuesday in New York City for the campaign, hosted by Donald Trump's wife, Melania.

Trump spokesman Michael Cohen said 400 people are expected at the event in the couple's residence inside Trump Tower. Cohen said the event sold out in a week, and is expected to bring in "well in excess" of $600,000.
Cohen said Trump will stop by the fundraiser to wish Mrs. Romney a happy birthday. He said Trump expects to host another fundraiser for the campaign at Trump Tower once Romney officially clinches the nomination.
First lady Michelle Obama will also be raising cash on Tuesday. She will speak at a Democratic National Committee event in Nashville, followed by two DNC fundraisers in Pittsburgh.
Tuesday will be a busy political day in Pittsburgh, as Romney holds a midday campaign roundtable at a community center in suburban Bethel Park.
