Singer Ashlee Simpson, who's currently pregnant, had enough energy for a night out in the town with her husband and singer Evan Ross. The two were recently spotted last Friday night as Ross was set to perform along with Simpson's ex, Ryan Cabrera in Hollywood.

It was pretty late for a pregnant lady to be out at 11:00 pm. Reportedly, Simpson and Ross arrived at The Hotel Café at 11:00 pm and stayed there until after a series of singers, including Simpson's ex, Cabrera and her husband Ross performed.

But of course, Simpson had everyone gushing with how well she is supporting her husband in his career. The slowly moving pregnant Simpson was seen to have seated in the front row of the venue as there was only one seat available at that time.

Several eyewitnesses reported that Ross was gentleman enough to have secured Simpson a seat before another available seat comes for him. Meanwhile, while many might think that there will be tension between the three celebrities, apparently there were none.

It was indeed quite the timing where Cabrera along with Emma Dewing, Mike Posner and Ross were all set to perform in one night. But Simpson's ex and the married couple had no chance of mingling according to an eyewitness of E! News. "Ryan didn't say one word to either of them and he was two feet from them," the eyewitness said. "He just got up on stage and did his songs and left."

It was indeed just a peaceful and fun night as Simpson was reportedly enjoying how everyone adored her husband in performing. "Ashlee cheered and smiled and acknowledged others who were tapping her on the shoulder in a 'he's great' kind-of-way," the eyewitness continued. "She'd then nod and smile."

Simpson, being a famous singer of 'Pieces of Me' also reportedly did collaborated with his husband which will be part of Ross' upcoming album. "We already did a song together and we're going to do more together," Ross previously told E! News. "We did an incredible song together but we're going to keep doing music together. She's unbelievable. Our voices sound really well with each other."
