Promiscuous girl Nelly Furtado had better learn to cover up — at least for however long it takes her to sing a couple of windchill-accompanied tunes during the 94th annual Grey Cup half-time show at Canad Inns Stadium Nov. 19.

Organizers announced yesterday the crop top lovin’ R&B songstress will head up the mid-game entertainment spectacle.

Furtado won’t be the only pop gal workin’ her thang on game day. The latest Canadian Idol winner, multilingual Gatineau, Quebec native Eva Avila, 19, has been slotted in to sing the national anthem in English and French — and Spanish, if necessary.

The Grey Cup date is one of many in Furtado’s crazybusy schedule of public appearances and tours supporting her album Loose, which has garnered international kudos and a smash summer hit, Promiscuous, since its release in June. Loose is Victoria-bred Furtado’s third album, following 2003’s Folklore and her 2000 debut, Whoa, Nelly! featuring her Grammy-winning breakthrough single I’m Like a Bird.

Furtado and Avila join a slew of already announced performers hitting various city venues throughout Grey Cup week.

Headlining at the MTS Centre are crooner Kenny Rogers (Nov. 15), Toronto grunge group Three Days Grace (Nov. 16), surf songsters The Beach Boys (Nov. 17) and Manitoba’s own Tom Cochrane with Red Ryder (Nov. 18).

Three authentic Manitoba socials — kubasa, rye bread and the whole bit — are being held at the Convention Centre Nov. 16 - 18, featuring homegrown country boys Doc Walker, retro rocker Sam Roberts and CanRock outfit 54-40.

Other Grey Cup Festival activities include a family day at The Forks followed by a downtown parade Nov. 18 and CupFest (Nov. 17 & 18), a late-night bash for music fans to check out hot local acts at a number of clubs within stumbling distance of each other. CupFest bands and schedules will be announced next week.

Tickets for most events are available at Ticketmaster, including the Grey Cup game itself, which has yet to sell out.
