The wife of North Korean leader Kim Jong-un is stirring speculation that she may be pregnant again.

In a recent photo released by North Korea's Rodong Newspaper, Ri Sul-ju was spotted wearing a similar baggy beige dress that she wore in October 2012 during her first pregnancy.

"Her face looks like she's gained weight and is wearing a baggy dress," said Chung Sung-Jang, a North Korea analyst at Sejong Institute in Seoul. "She seems to be three to five months pregnant and if so, is likely to give birth this summer." But he added that her baby bump is "not visible enough to be definitive but time will tell."

The Kim family has ruled North Korea like a dynasty and Kim Jong-un is the third generation to be the country's leader since its creation.

Ri gave birth to a daughter last year.
