--->What is the problem with 'ParametricPlot'?

I input the followings:
x={Sin[t]}^3
y={Cos[t]}^3
ParametricPlot[{x, y}, {t, 0, Pi/2}]
And got the following outputs:
ParametricPlot::ppcom:
Function x cannot be compiled; plotting will proceed with the
uncompiled function.
ParametricPlot::ppcom:
Function y cannot be compiled; plotting will proceed with the
uncompiled function.
ParametricPlot::pptr:
x does not evaluate to a pair of real numbers at t = 0..
ParametricPlot::pptr:
x does not evaluate to a pair of real numbers at t = 0.0654498.
ParametricPlot::pptr:
x does not evaluate to a pair of real numbers at t = 0.1309.
General::stop:
Further output of ParametricPlot::pptr
will be suppressed during this calculation.
Can anyone tell me what is wrong?
Thanks in advance!!
Seagull.
