The secret is out.

Limited Brands ( LTD) shares rose in premarket trading Tuesday after the retailer said strong sales at its Victoria's Secret unit prompted it to boost first-quarter earnings and sales guidance.

The company now expects earnings of 11 cents to 13 cents a share, above the consensus estimate of 10 cents a share, according to Thomson One Analytics. Previously, the company offered flat guidance.

Limited also forecast that same-store sales for the five-week period ending April 3 will be in the low double digits, vs. a previous forecast of mid-single-digit growth.

The Ohio-based retailer said its Bath & Body Works chain also had a positive, though lesser, effect on the improved sales and earnings guidance.

The company did not release any specific sales figures for any of its retail chains.

Shares were up 60 cents, or 3%, to $19.89 in premarket trading.
