Newly single Hayden Panettiere rocks a couple of tiny bikinis in the new issue of Esquire magazine, heading up this month's Joke From A Beautiful Woman feature.

The joke isn't that funny (watch it below), but the Nashville star's photos make up for it.

Hayden recently split from boyfriend Scotty McKnight, who she began dating shortly after breaking up with Russian Wladimir Klitschko last year. In addition to losing Panettiere, McKnight was recently cut by the New York Jets, so things are going REALLY bad for him of late.

There is a slight ray of hope though -- an insider told TMZ.com that the couple "will probably be back together sometime down the road."

The January issue of Esquire hits newsstands December 18th and features a Sean Penn cover story. See more pics of Hayden in her bikini on page 2 and at Esquire.com.
