It’s a special first for Jesse & Joy…

The Mexican pop duo, comprised of siblings Jesse Huerta and Joy Huerta, has earned its first No. 1 on Billboard’s Top Latin Albums (chart dated Dec. 26).

The announcement comes as Jesse & Joy’s,Un Besito Mas arrives at the top spot with 3,000 copies sold during the tracking week ending Dec. 10 (according to Nielsen Music).

The entry marks the fourth charted set for the Mexican siblings who first reached the tally in 2009 with Electricidad (No. 14 peak).

Meanwhile, single “Ecos de Amor,” from Besito, hops 35-32 on the Billboard Hot Latin Songs chart in its 12th week.

When the track debuted on the Oct. 10-dated chart, it ended a 22-week run of having no female-led songs on the chart. “Ecos” peaked at No. 30 (Nov. 7).

Over on Billboard’s Latin Pop Songs, chart the pair net the highest weekly debut with the set’s second single, “No Soy Una De Esas” featuring Alejandro Sanz. The song arrives at No. 19 — the act’s best entrance to date (of 15 charted songs). “Ecos” concurrently slides 19-24 on the list.
