Jessica Simpson threw a baby shower for her best friend on Sunday (02.06.13).

The singer - who is expecting her second child with fiancé Eric Johnson in July - took focus off her own pregnancy in order to throw her close pal CaCee Cobb a lavish party at the Four Seasons Beverly Hills.

CaCee, 35, appeared to be very grateful for the baby-themed bash, writing on Twitter: ''Showered with so much love yesterday, Thank you @JessicaSimpson #bestfriends #bestbabyshowerever (sic)''

The pregnant pals, who are due to give birth just a month after one another, also posed for a picture showing off their growing bumps, with Jessica, 32, sporting a slimming black dress.

CaCee - who was the 'Irresistible' singer's personal assistant for many years - is expecting her first child with 'Scrubs' actor Donald Faison, whom she wed in December 2012.

Meanwhile, Jessica and Eric will be adding to their brood just a year after welcoming daughter Maxwell into the world.

It's thought the 'Fashion Star' judge - who became engaged to Eric in 2010 - is keen to tie the knot as soon as possible after giving birth as she fears she may fall pregnant again and be forced to cancel her wedding plans a third time, having previously nixed their nuptials because of the unexpected baby news.

A source said: [Jessica] was telling friends she wanted to get married a few months after the baby is born.''
