The Hills: New Beginnings: Heidi Montag breaks down to Ashley Wahler about ...

Heidi Montag broke down at Kristin Cavallari's cocktail party when she revealed to Ashley Wahler that maybe jealousy over her pregnancy was the reason why she along with Spencer didn't attend her baby gender reveal party.

'I'm trying to get pregnant and that's not really happening for me,' Heidi tearfully admitted to Ashley 32, that she had a lot of her own stuff going on.

'I see you're hurting and you are not explaining it' said Ashley. Ashley told Heidi she was hurt that she didn't come to her party because they knew it was also Jason's sobriety party. Ashley said she didn't understand the issue between them.

'Let's just keep it calm because you are pregnant,' Heidi told her. 'I did hear you said a lot of bad things about me which is why I didn't come.'

Ashley admitted that on their San Diego trip that she was very annoyed by everyone who was drinking. She said she was nauseous and couldn't drink. 'And you were being annoying,' Ashley told her bluntly.

The episode titled 'I'm Back In LA Bitches!' Kristen Cavallari came back to town to get the friends together but when the drinks started flowing the cocktail party in her honor got messy.

Earlier in the episode, Spencer Pratt, 37, met Brody Jenner, 37, for some Mexican food. Spencer was starting his diet on Monday so he ordered many of the items on the menu. Brody decided to have a margarita. In his confessional, he said he took six months off from drinking but that now he could let himself have drinks on special occasions.

'I think it will be okay if I stay in my lane,' Brody said. Brody reminded Spencer that they used to drink a lot and that he once almost lit Nobu on fire. Spencer said they had given him a flaming shot and that he sat down then with Jennifer Aniston right after she just broke up with Brad Pitt and that he said to her 'Its okay that's Angelina is horrible.' Spencer said she just looked at him.

'That was some fun times, man,' said Brody. 'I picked up so many bad habits over the years.'

Brody then wanted to know why Spencer and Heidi didn't go to Ashley Wahler's baby reveal party. Spencer said the reason was because Audrina Patridge, 36, told his wife Heidi Montag, 34, that Ashley was 'talking all this sh** about her.'

Spencer then told Brody that Audrina can't keep secrets and that he knew all about Brody and Audrina.

'I'm curious I would love to hear this,' said Brody.

Spencer said he didn't feel welcome at Ashley's party because she had said something about Heidi. Spencer then told Brody that there were two Jason[Wahler's] and that he found him hypocritical. He said last time he saw Jason, 34, that he told him he was sober, but he wasn't. Spencer said he wasn't cool with Jason. He said that Kristin Cavallari, 34, was back and 'she was on fire.'

Audrina met up with Kristen at her AirBnb house and they opened a bottle of champagne to celebrate. When the cork widely popped and the bottle overflowed, Kristen declared 'I'm back in LA, bitches.' Kristen said she was happy to catch up with friends. She said because of her divorce she had more free time.

'For the most part, I feel really free and I'm really happy ,' Kristen told her. 'Overall, I'm actually doing really well.'
