How to retrieve field names from temporary table (SQL Server 2008)

I'm using SQL Server 2008. Say I create a temporary table like this one:

create table #MyTempTable (col1 int,col2 varchar(10))

How can I retrieve the list of fields dynamically? I would like to see something like this:

Fields:
col1
col2

I was thinking of querying sys.columns but it doesn't seem to store any info about temporary tables. Any ideas?

select * from tempdb.sys.columns where object_id =
object_id('tempdb..#mytemptable');

select * 
from tempdb.INFORMATION_SCHEMA.COLUMNS
where table_name like '#MyTempTable%'

The temporary tables are defined in "tempdb", and the table names are "mangled".

This query should do the trick:

select c.*
from tempdb.sys.columns c
inner join tempdb.sys.tables t ON c.object_id = t.object_id
where t.name like '#MyTempTable%'
