They're calling it "An Afternoon in Havana," at the Coliseum in downtown St. Petersburg, but the hottest part might be the hosts — namely Maks Chmerkovskiy of Dancing With the Stars bad-boy fame. He'll be joined by Mary Murphy (So You Think You Can Dance) and DWTS's Tony Dovolani. The music's not bad either. Orquesta Aragón is a Cuban band whose lineage goes back to the glory days of Havana nightlife. The party celebrates the end of the five-day Millennium Dancesport Championship that's taking place at the Marriott Tampa Waterside this week, where the trio is serving as judges. The dance championship runs through Saturday with top competitors from around the world; $25-$150; (863) 668-9668; 8 a.m.-8 p.m. today, 8 a.m.-7:30 p.m. Friday-Saturday. At the Coliseum party, which is from 2 to 6 p.m. Sunday, there will be Latin dance stars, Cuban food and drink, plus a courtyard for cigar smoking. Tickets for reserved table seating are $70-$145.
